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

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.

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.

The concept of thermoplastic elastomer

1.The concept of thermoplastic elastomer

Thermoplastic elastomers (TPE), sometimes known as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers.

2.the types and Detailed introduction of TPE

TPE is the general term of thermoplastic elastomer. According to the different structure unit of raw materials, TPE Elastomer can divide into four types, including: Thermoplastic Elastomer(TPE), Thermoplastic Rubber(TPR), Thermoplastic Polyrethane(TPU), Thermoplastic Vulcanizate(TPV). The most common, most used for various applications in large quantites among these types of elastomers is TPE. so we will emphasis on the information about TPEs.

1.1 Styrene-polystyrene elastomer:TPE

TPE-s is one type of thermoplastic elastomers which base on SEBS and SBS.we usually called TPEor TPR(thermoplastic rubber).

1.2 The Basic properties of TPE-s

TPE has the basic propertied of Thermal plasticity processing of plastic and elasticity of rubber so we can adjust the hardness to have a comfortable touch feeling.
