How to identify the TPR sole

Each TPR is the most common and most common materials.

But in daily life, many people do not know this pair of shoes to wear on the foot Is it right? Belongs to what we say TPR material, then I will teach you a few strokes of the most simple method of identification.
To find TPR first and other different outsole material to distinguish. Such as PVC and PU or rubber etc..

1, there are a lot of people can’t tell PVC and sole actually these two kinds of materials easy to recognize TPR, PVC, TPR to be heavy in the hand than the sole material. The elasticity of the sole TPR material is better than PVC, is the most simple method, the sole firm hold, the natural fall if you can bounce back word is TPR, PVC. Material sole is TPR cheaper, but quality is not good, especially in the winter, very easy to break the bottom.

2, the identification of rubber bottom is also very simple, Rb bottom has a characteristic that is not an injection hole, and the nose to smell it, taste put longer words will long color to white material things.

The surface of the sole is light, TR 3. Compared with the general TPR sole to some hard. Multiple injection hole injection holes TR TPR is very special.
In fact, is not difficult to recognize these materials contact more, see at a glance soles will know what is the material of the.
Summary: in short, as long as you combine several appeal list, plus daily of careful observation and experience it is not difficult to identify.

Thermoplastics For Shoe Inserts

Shoe inserts are increasingly popular among not only those who spend a great deal of their days on their feet, try but among those who require therapeutic support when walking. The construction of these inserts requires that they not only provide a comfortable cushion, but that they retain their shape even after repeated use. This is why thermoplastic elastomershttp://www.gainshine-tpe.com/ are so useful for shoe inserts, providing solutions that make people’s lives easier.

TPEs by their very nature are ideal for shoe inserts. As the substance is elastic by design, and when used in its super-soft gel form, it is able to stretch and mold itself to the foot of the wearer – an ideal situation when choosing rubbery shoe inserts. Because of the thermoplastic properties, though, the material is also able to retain its original shape after usage, allowing the inserts to be useful over and over again. Indeed, thermoplastics make for an ideal choice in any type of shoe insert.  Look to TPE gels for providing your customers with the utmost comfort while still guaranteeing utility.

Thermoplastic elastomers are used for more than comfort in the industry, though. Physical therapists recommend the use of the material in orthoses for their clients, and the nature of the substance makes it ideal for those who suffer from extreme pain or who require the inserts for their mobility. Many of the major orthotic manufacturers use TPE gel in their products for this reason, rendering their footwear not only comfortable for the end user but also therapeutic.

TPE Overmolding and Bonding

Design engineers choose TPEs for improved ergonomics, enhanced grip performance, improved aesthetics, and critical impact protection. Applications that benefit from TPE overmolds range from consumer goods to medical insruments to industrial tools and can include knobs, handles, gaskets, seals and grips.Benefits of Overmoldingtoothbrush.

With improvements in TPE materials technology, overmolded part designs have become less dependent on mechanical interlocks to hold a TPE in place. Chemical bonds between TPE and rigid materials offer improved part integrity and longevity while eliminating the need for adhesives or surface pre-treatments. System performance can be further optimized by including both chemical and mechanical bonds in the part design. The net benefit is greatly expanded design freedom.

Chemical bonds in Overmolding:
Improve product function
Increase margins
Expand product differentiation
Enable new design innovation

TPEs can match TPV performance

New styrenic thermoplastic elastomers are said to perform similarly tothermoplastic vulcanizates in window gaskets.

Its new series of GainShine TPEs also have advantages over TPVs, such as less — or no — die drool duringcoextrusion of the window gasket and resistance to staining from paints. Compounds in the GS E5 series adhere well to the polypropylene or high-modulus TPE substrate that serves as the rigid supporting component in weatherproof seals in PVC, metal and wood window frames.

Some grades in the series can be processed with the same tooling as PVC profiles at similar throughput rates and die pressures. Rubberlike seal recovery, low-temperature toughness and UV resistance of the GS E5 series provides resistance to moisture and air demanded in this application.

Areas of growth exist for global TPE market

The global thermoplastic elastomer market is maturing in some sectors, but still has areas of growth, Some TPEs are viewed as commodities, and their growth is slowing. The structure for those TPEs is shifting because of price pressure and overcapacity and There’s saturation in some market sectors.

Use of thermoplastic polyolefins (TPOs) in auto bumper fascias and of thermoplastic polyurethanes (TPUs) and styrenic block copolymers (SBCs) in footwear are two TPE uses that are at the saturation point.

Uses of various TPEs for “soft touch” in sports, appliance, leisure and tool markets are areas that are mature and close to saturation.

TPEs still have many opportunities in the auto market.

Performance standards are changing, and that creates new opportunities. Thermoplastic vulcanizates and SBCs are challenging EPDM materials in auto glazing seals. TPEs also are moving into door seals and trunk seals. And even a basic market like floor mats presents a 300-million-pound opportunity for SBCs.

In the medical market, TPEs continue to see high growth despite early penetration. Prices for TPEs sold into medical applications can be two to three times higher than those sold into commodity applications. SBCs have been dominant in TPE medical uses, but copolyesters also have found a home in breathable films and gowns.

And although emerging market growth has slowed in recent years, China and India remain growth markets for TPEs.

Weight Reduction of Material – Interpretation of Industry Trend of K Messe 2016

In transportation, light weight is widely recognized as the key to reducing energy and fuel. Manufacturers of machinery for the plastics industry, manufacturers of plastic box enhancers, research institutes and plastic processors are working on large-scale production of lightweight components, particularly in the automotive and aircraft sectors.

In order to achieve mass production of lightweight components, special production methods, particularly reaction and injection molding technology, need to be integrated together to find the right solution.

Lightweight plastics or fiber composites, and polymer materials with matrix polymer reinforcement fibers and substrates can fast produce weight-optimized components with maximum processability.

In addition, K 2016 will show metal-plastic blends and polymer-fiber reinforcements. Thermoplastics, thermosets, and bio-based polyurethane substrates are being blended with glass, carbon and other synthetic or natural fibers to meet the requirements of modern applications. Substrate materials must meet flame retardant regulations, but also need to provide superior mechanical properties and fluidity, and fiber and matrix materials must provide adequate bonding properties.

By then, visitors can also see the gradual progress of lightweight multi-stage production process, including reinforced fiber and flexible materials, automated processing.

Conclusion: lightweight materials, whether it is in consideration of energy-saving, load-bearing or raw material costs, etc., have shown a new trend in the development of materials. To TPE's, currently the horn of weight reduction has been blown already. For example in the industry, micro-foam technology has now been widely used to reduce the density of materials.

Thermoplastic Elastomer (TPE) vs. Thermoset Rubbers

GainShine Plastics offers softThermoplastic Elastomers (TPE), a versatile flexible material available in multiple durometers. Thermoplastic Elastomers are a more environmentally friendly option to Thermoset Rubber and is widely used in the medical and automotive industry.

Thermoplastic Elastomers are generally low modulus, flexible materials that can be stretched repeatedly to at least twice their original length at room temperature with an ability to return to their approximate original length when stress is released. The grandfather materials with this property are thermoset rubbers, but many families of extrudable thermoplastic elastomers (TPEs) are replacing traditional rubbers.

Benefits of TPE’s Vs Thermoset Rubbers

Design Flexibility
Lower fabrication costs
Scrap is recyclable
Better control of product quality
Broader range in product density
More environmentally friendly

There are a wide variety of TPE’s available to meet your industrial or medical application, available in clear or colored to your needs.

GainShine develop TPE materials in medical caster

Various casters in daily life, such as baby stroller casters, luggage casters, industrial shelves casters,these products are usually based on rubber, foaming-EVA, PU and other materials with bad smell and noise. This makes the impetuous society seem more noisy, noisy.These plastic materials are out of step with modern life.

Compared with the daily casters, casters used in the medical industry has no bad smell and meet the requirements of medical industry perfectly. It there any secret?

Actually,medical casters are used a kind of environmentally friendly/non toxic/ odorless thermoplastic elastomer(TPE) material as the tire skin of casters.

A lot of buggy casters are use vulcanized rubber or foaming-EVA material, so led to bad smell and problem of environmental protection. And a lot of industrial casters and luggage casters are use PU as the tire skin of casters. Although PU with strong wear resistance,it also make large noise.in the use of the rolling process, too much noise.

We do not add sulfur, DCP and phthalate plasticizers to TPE material in the processing,so TPE is a completely non-toxic material.And thermoplastic elastomer(TPE) material has flexible molecular chain structure and small friction coefficient so . At the same time, the TPE material has special styrene butadiene block structure, which ensures that the material has high strength and wear resistance proporty. That is why TPE is the best choice for medical caster now.

This kind of silent casters, in addition to the application in medical industry, also in some high-end restaurants, the airport waiting hall and other places, are so popular.

Why more and more factories choose TPR material to producing pet toys ?

With the development of the world economy,people's living standard have been improving.people began to seek spiritual comfort.Many countries have entered an ageing society,more and more elderly and kids need pets to acompany with them and they are willing to spend lots of time and money to take care of them and buy anything needed.In recent years, the industry has made rapid development.

The news said that TPR plastic dog toys are the most popular in the market of pet toys,Followed by absorbent pads and Christmas dolls.pets are usually regarded as members of family and they are looked after carefully by their masters.Compared to the price, they pay more attention to the style and quality of pet toys.

Why they always choose TPR materials for pet toys? TPR, also known as thermoplastic rubber, has a elastic properties of rubber, with excellent wear resistance and tear resistance, feel comfortable.TPR materials have through the third party testing and certification,conform to RoHS, reach (SVHC), EN71, does not contain plasticizers phthalates, bisphenol A, does not contain nonyl phenol (NP), does not contain polycyclic aromatic hydrocarbons PAHs.TPR is fully in line with the environmental testing standards of foreign market.so TPR materials is the best choice for pet toys.

PVC, silica gel and TPE-which is the best choice for sex toys ?

As sex toys are direct contact with human sexual organs, for the protection of the body, it is more important to Pursuit real sexual experience, These requir the raw material of sex toys must be very soft and healthy for body.the most common soft raw material including: PVC, silica gel and TPE (Thermoplastic Elastomer). different uses of sex toys,different hardness of the raw material. some dildos and vibrators for woman usually using the soft material of 5-20 shore A and the processing is injection molding.But some Male Masturbators usually using the ultra soft TPE material of below 0 shore A(such as:000 or even 00000) and the processing are injection molding and pouring. The pouring is usually used for the large size male sex toys.Let's talk about the Advantages and disadvantages of PVC, silica gel and TPE for sex toys.

Look at PVC first. PVC is a polyvinyl chloride resin,we can let the hardness of PVC drop to very sofe by adding a large number of plasticizer (usually phthalate plasticizer DOP) even 0 shore A.The advantage of PVC: low price, Bright color, can be rapid injection molding processing.The disavantage: bad smell, the most important is that plasticizer is poisonous. Although PVC is not directly contact with the human oral airway, people always worry about the safety.Some high-end sex toys always using more More environmentally friendly materials but not PVC. What is more,for some sex toys of blow 0 shore A, PVC is difficult to reach the ultra soft touching.

Look at the silica gel. Chemical element of silica gel is a silicon and oxygen, does not contain benzene toxic molecular structure, crosslinking agent of silica gel usually uses the environmental protection of varieties. Therefore, silica gel is a very environmentally friendly soft material. For a long time, silica gel is the most common soft material used in the dult products. The hardness of silica gel for adult products can be adjusted in 0~20 shore A. The disadvantage of silica gel:high price, long molding cycle, and the raw material can not be recycled.

Finally look at TPE/TPR. soft material TPE for sex toys is based on SEBS , we usually use the environmentally-friendly operating oil as a modifier to adjust the viscosity and hardness of SEBS. The formulation system is relatively simple because it is a super soft material for use in sex toys. TPE is a environmentally-friendly soft material and its constituent components-SEBS and operating oil do not contain plasticizers which can pass the detection of o-phenylenediamine 16p, nonyl phenol (NP), polycyclic aromatic hydrocarbons PAHs. The hardness of TPE can be adjusted to be softer than silica gel so TPE is the ideal raw material for sex toys. some TPE sex toys may be a little sticky feeling, there will be a certain smell because of the oil, we can add some Smoothing Agent and flavor to improve the properties. The advanatge of TPE: moderate price, Recycling materials, safety.

In general,if you really care about the price and have few requirements for the raw material,PVC is a choice for you.If you care about the experience and the environmental protection,silica gel and TPE are better than PVC. However,the price of silica gel is higher than TPE.As far as I'm concerned,i think TPE is the best choice for sex toys.

What is TPE + PE ?

There is a very meaningful sentence which I saw by accident today-PE+TPE.OK,what is the really mean of PE+TPE?PE is a hard plastic and TPE is a elastomeric plastic.when they are mixed together, what will happen next.

PE+TPE, one of the possible meaning is that one product contain two kinds of thermoplastic materials:PE and TPE.These two kinds of materials are used for different functions components.first of all, injected PE into mold, and then injected TPE(thermoplastic elastomers) above PE(adhesion to PE).When you walk in a large supermarket ,there are some words (PE+TPE or TPE+PE) on the surface of some plastic commodities,like:handles.In addition,Co-extrusion film and Co-extrusion extrudate are also composite products made by TPE+PE.

PE+TPE, another possible meaning is that some customers want to add some TPE into PE in order to decrease the hardness of PE and improve the flexibility of the material .This products of TPE modified PE, such as some cosmetics bottle cap, water dispenser plastic cover,Disposable gloves for medical use…

PE solubility parameter Sp=8.0, TPE solubility parameter Sp=7.2. The two values are relatively close.From the similar compatibility principle, PE and TPE should have good Blend compatibility.

Just one step to distinguish TPR, Silica gel and PVC

TPR, Silica gel and PVC,they resemble each other both in appearance and touch.It is so hard to distinguish for someone who is not familiar with these. Thermoplastic Rubber (TPR) Compounds that are available for a wide-range of applications. These compounds are formulated using Styrene-Butadiene-Styrene (SBS) .But TPR is not silica gel,they are different material.Now i tell you just one way to distinguish TPR, Silica gel and PVC.  

If you want to distinguish these three materials,you just need one Lighter.You just need to burn it by lighter.Then,pay attention to the color of flame and the smell of burning.

TPR: burning phenomena-The main body color of the flame is yellow, and the root of the flame is blue. Smoking smell:lighter or thicker smoke,fragrant smell.

Silica gel: burning phenomena - The main body color of the flame is bright white. The smoke and the smell of burning are light, and there is a clear white ash residue after combustion.

PVC : burning phenomena - The main body color of the flame is yellow,and the root of the flame is green.smoking smell:black and Dense smoke,bad smell (the smell of chlorine).

The real reason why carpet should choose TPE material

Nowadays,Rubber and PVC are replaced gradually by TPE because many advantages of TPE material.At present, TPE (thermoplastic elastomer) is gradually used in the carpet industry. Then let’s look for the advantages of TPE materials compared with other plastics !

Environmental protection and nontoxic
Compared with the PVC material, PVC material carpet’s smell is too heavy, sometimes even contain toxicity:phthalate phthalate ester plasticizers and heavy metals. TPE material carpet:no peculiar smell, non-toxic and environmentally friendly, and even meet the FDA food grade standards.

Low temperature tolerance
low temperature resistance of TPE is better than PVC. TPE material will not become harder and keep elastic and non slip at the low temperature -50℃.And PVC will lose elasticity at the temperature of -10 ℃ . In some outdoor environment of low temperature, TPE carpet is no doubt better than the PVC carpet.

Requirement of carpet for TPE materials
1.TPE can be adhesioned to carpet very good and not sticky to roller.
2.High mechanical strength
3.No oilimpregnate when pakage
4.Can be dry at low temperature

Therefore, we know that TPE has become the first choice for carpets, The PVE material has been gradually fade out of the market.As a substitute,TPE has very many unique superiority,In the future TPE will certainly be able to do better.

Let us talk about low density and super-light TPE/TPR materials

Recently,i realise that more and more customers have high demand for low density and super-light TPE/TPR materials. For what motivations,one is based on the light weight of the material , which is relatively portable for the user;two is reducing the density of materials and cost of raw materials,three is other sepcial requirments.

Generally speaking,the density of TPE(Thermoplastic Elastomer)/TPR is about 0.88-1.3.Transparent TPE/TPR materials with no filler is about 0.88-0.95 belong to floating material. but this density mustn’t come up to the standard of super-light TPE/TPR materials.at present,there are some low density TPE/TPR materials appeared in the market which density is about 0.6-0.8,some industry insiders even said that the lowest density can reach to 0.3-0.5.anyway,According to the current technology of TPE industry, foam is an inevitable way to produce ultra light TPE material,so let us talk about the foaming TPE/TPR materials.

According to the different products of foaming TPE,we can use the way of injection molding or extrution to process.
Chemical foaming is better than Physical foaming because Physical foaming has very high demands on machine and the higher investment.

Requirements for TPE materials
Suitable hardness:60-80 shore A,high Melt Strength,no filler

The foaming agent.
It is the best to use HYDROCEROL BIH or EXOCEROL232 but not foaming agent AC.foaming agent AC has so many disavantage,such as: Fast heating,easy to melt fracture, roughness surface.

Do you know high temperature resistant properties of all kinds of thermoplastic elastomer TPE ?

For plastics and hard rubber,we usually use HDT Tester (VEKA temperature) to determine the High temperature tolerance.there are two calibrated parameters:one is Heat deflection temperature,the other is Vicat softening temperature. Classically, Heat deflection temperature is lower than Vicat softening temperature.

But for thermoplastic elastomer(TPE) industry,because of many kinds of TPE,many formulations,different adjustable hardness and property.there isn't any occupation standard to test the property of High temperature resistance.The following table, i make stocktaking of all types of thermoplastic elastomer TPE (including silica gel) for the high temperature resistance.

In the table, Silica gel has excellent high temperature resistance.However, silica gel is cross-linked elastomer which structure is different than thermoplastic elestomers(TPE) and thermoplastic elastomer TPE structure is different,I think the biggest difference is Silica gel can not be recycled but TPE can be.TPUE-SH in the table is a new products developed by our company in 2016 which is a thermoplastic elastomer has high temperature resistance.

TPUE-SH (thermoplastic elastomer) has excellent high temperature resistance(160-200℃), can be processing directly by injection molding machine. Because it is thermoplastic material, it can be completely recycled. TPUE-SH has excellent resilience,Good resistance to permanent deformation, texture smooth surface, excellent scratch resistant performance.what is more,TPUE-SH can be adhesion to ABS, PC, PC+ABS (overmolding) and replace silica gel/rubber.which also can be used in seals,push-button and some soft plastics has high requirment on high temperature resistance.

The difference and conversion between Shore(A) and Shore(D)

Generally speaking,Shore(A) is used to measure the hardness of soft plastics or rubber,Shore(D) is used to measure the hardness of hard plastics or vulcanized rubber.The shape of indentor from A-form sclerometer is frustum cone and the shape of indentor from D-form sclerometer is conical.

Test method of Shore(A) and Shore(D) are different.It could not be converted between them in the ordinary way.So if you want to measure plastics under 90 Shore(A),A-form sclerometer is  the best choice. If Higher than 90A,D-form is the best.

But we have two kinds of approximate conversion method.

   1、 D=A-50  ；

   2、A=0.173D+86.58.

If you want accurate hardness, it is recommended to use the A-form sclerometer for soft plastic, D-form sclerometer for hard plastics.

BTW:other special presentation options of hardness.

1.Shore(C):it is usually used to measure ultrasoft plastics which hardness is under 0 Shore(A),The hardness of Thermoplastic Elastomers(TPE) and
Thermoplastic Rubber(TPR) which has good Oil absorbing can be made to under 0 Shore(A)

Drying temperature and drying time of TPE materials

Water absorption of TPE materials is very small,about 0.3-0.5%.In the ordinary way Drying is not required under injection molding directly.For some products which need overmolding,you should need to dry it before Production and processing,such as after prolonged storage to achieve best results use on dry 2 hours at 70℃ .

Drying temperature and drying time of TPE materials:
TPE: hardness:30-60 shore(A),Drying temperature:60-70℃，drying time：1-2h.
TPE: hardness:70-100 shore(A),Drying temperature:70-80℃，drying time：1-2h.
The general principle of drying: higher hardness of TPE,higher Drying temperature,longer drying time.

Do you really understand the market of halogen free & flame retardant TPE

TPE (based on the SEBS substrate) conventional compound system, the flame retardant rating is HB (energy). However, with the expansion of the application field which has high demand for the performance of TPE. The emergence of flame retardant TPE, Let TPE can be used in the field of electronic materials, wire and cable field of Traditional technology by traditional processing.The key raw material is halogen for flame retardant , when you burn the halogen combustion,it will release of dioxin gas. cause tremendous pollution to enviroment. Some big company,like:apple, Dell, Sony, Samsung and other large enterprises are ban on using the materials including halogen.

In recent years, the research and development of halogen free and flame retardant TPE in China is in full swing, although a number of domestic TPE production enterprises have claimed that the halogen free flame retardant TPE material can be provided to used in the field of wire and cable.due to the pecial application of halogen free and flame retardant TPE,has high requirements on the formula and technique of TPE. Although all the TPE factory say that they can provide the halogen free and flame retardant TPE, just for the promotion.Only a few large companies can really provide the mature and stable products of flame retardant TPE.

Transparent TPR material for shoes and sole

Generally speaking，there four kinds of hardness for transparent TPR material,like:5 (shoreA),10 (shoreA),15 (shoreA),35 (shoreA) which can be injected for shoes and soles. TPR materials are applicated for sole including three main insole accessories:one is half sole pad,two is Heel pad,three is the entire shoe pad.

Half sole pad(actual picture)

Half sole is on the position of feet,the thickness of produce is 2~3mm so we need the soft and smooth TPR materials and not tacky.Therefore, we usually use transparent TPR material which based on SEBS. Hardness is usually about 5~10 shore(A).

Heel pad(actual picture)

Heel pad is mainly to play the role of shock absorption and increased.the thickness of produce is 5~20mm, hardness is about 15~35 shore(A).consider with the adhesion of the soles, can use TPR materials which based on SBS.

Entire shoe pad(actual picture)

The transparent shoe pad mainly plays the role of shock absorption and increase comfort, the general thickness is 2~3mm, and the hardness of the material is 30~35 shore(A). Insole products has a high requirments on the tensile and tear strength.What is more,insole and sole easily can be adhesive by glue. so usually choose transparent TPR material which based on TPR materials and add some RB toughening agent to improve the toughness and tensile properties of materials.
