How to choose a TPR material supplier in Beijing

TPE overmolding injection generally adopts a two-shot injection molding process.

To prevent contamination of TPE raw materials and the presence of old material or impurities in the recesses of the screw and attachments, especially materials with poor thermal stability, before use and after shutdown, all parts should be cleaned with a screw cleaning agent to ensure no impurities adhere.

SEBS is the product of SBS after hydrogenation. SEBS has a saturated molecular structure, which leads to its very different characteristics. It possesses the necessary aging resistance and yellowing resistance required for producing transparent TPE, and also promotes excellent properties such as high temperature resistance and corrosion resistance. Only then can transparent TPE be manufactured.

Fix the injection-molded rigid plastic parts onto the overmolding mold, then inject and bond the TPE soft material onto the rigid parts at an appropriate temperature, and cool to obtain the product. The injection temperature for overmolding depends on the hard plastic material being overmolded.

TPE overmolding injection generally adopts a two-shot injection molding process, that is, fixing the injection-molded rigid plastic parts onto the overmolding mold,

The transparent grade includes transparent and translucent series, each with various hardness levels; excellent transparency; smooth and soft surface; good yellowing resistance, tear resistance, and tensile strength; meets environmental requirements; suitable for various transparent series products.

Due to the high light transmittance required for TPE transparent materials, strict requirements are imposed on the surface quality of the material products. There must be no defects such as streaks, air bubbles, whitening, haze, black spots, discoloration, or poor gloss. Therefore, throughout the injection molding process, great attention and strict or even special requirements must be placed on the TPE raw materials, equipment, mold, and even product design.

TPE material has good fluidity and is mainly used for injection molding.

Diene type transparent TPE, diene type TPE is mainly an isomer of natural rubber, so it is also called thermoplastic trans-natural rubber. Although its heat resistance and mechanical strength are not as good as rubber, it is widely used in footwear, sponge, optical films, and other industrial rubber products due to its good transparency, weather resistance, electrical insulation, and photodegradability.

Styrene type transparent TPE is widely used in the footwear industry, having largely replaced rubber; at the same time, its applications in industrial rubber products such as rubber sheets and rubber plates are also expanding.
