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.
