How to select Tianjin TPE thermoplastic materials

TPE elastomer soft gel can be adjusted to the appropriate hardness (hardness range Shore 25-90A) according to the product's physical property requirements,

TPE is a classic aggregation-induced emission molecule, which means it has no fluorescence in solution but exhibits strong fluorescence in solid state. Therefore, transparent TPE materials also have important applications in fields such as organic optoelectronics.

Transparent TPE is used in appliance housings, handles, grips, etc. It exhibits very good hand feel, is anti-slip and labor-saving, and is easy to color and process. It also offers a wide design space.

and appropriate physical properties (such as wear and scratch resistance, adhesion, melt flow index, etc.). It provides various approximate material application plans for different products.

With the rapid development of the TPE elastomer industry in recent years,

The thickness of the TPE/TPR overmolding layer. In most overmolding applications, a wall thickness of 1.5-3.0mm will ensure good adhesion. If the TPE layer is too thin, injection molding is more difficult, adhesion strength is low, and hand feel is poor. If the TPE layer is too thick, on one hand the cost is higher, and on the other hand defects such as sink marks and bubbles are prone to occur.

Transparent TPE, specifically, is a thermoplastic elastomer, while TPR is translated from English and strictly speaking is called thermoplastic rubber. This is the most basic difference. TPE is generally modified and shaped from the basic material SEBS, while TPR is modified from the basic material SBS.

The application of TPE overmolding via two-shot injection molding is also becoming increasingly mature. Many hard plastic products, by incorporating soft elastomeric TPE materials, have improved touch, grip, aesthetics, and other functional properties.

Why is TPE material a good choice for toy dolls? Thermoplastic elastomer TPE soft compounds are becoming increasingly common in the toy industry. In the application field of toys,

Transparent TPE materials, due to their high light transmittance, require strict surface quality of the product. There must be no defects such as streaks, pores, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, throughout the entire injection molding process, strict and even special requirements must be paid attention to regarding the TPE raw materials, equipment, mold, and even product design.

Olefin-based transparent TPE has good weather resistance and ozone resistance, so it is called the fastest developing variety of TPE, and it is mainly used as a primary rubber material in fields such as automotive and home appliances.

Traditional soft PVC and TPR materials, with their good environmental protection, safety, non-toxicity and other characteristics, are increasingly welcomed and trusted by consumers. Each industry has its own corresponding standards. As far as the toy industry is concerned, it also has its own special industry standards.
