How to choose custom thermoplastic TPE in Tianjin

TPE materials are used in overmolding, with TPE soft rubber as the outer soft coating,

TPE is a classic aggregation-induced emission molecule, meaning it has no fluorescence in solution but strong fluorescence in solid state, so transparent TPE materials also have important applications in organic optoelectronics and other fields.

Styrenic transparent TPE is widely used in the footwear industry, largely replacing rubber; at the same time, its use in industrial rubber products such as adhesive tape and rubber sheets is also expanding.

Custom thermoplastic TPE

Common rigid materials that cooperate include plastics, as well as metals and fabrics. TPE overmolding with fabric is mainly used in luggage products, and like metal overmolding, it is generally false overmolding.

PP overmolding is a plastic with very weak polarity, and its polarity is very close to that of SEBS-based TPE.

To prevent contamination of TPE raw materials and accumulation of old materials or impurities in screw and accessory depressions, especially materials with poor thermal stability, it is necessary to clean all parts with screw cleaner before use and after shutdown to ensure no impurities adhere.

Transparent TPE materials, due to their high light transmittance, require strict surface quality of the product, without any defects such as streaks, pores, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, careful attention and strict or even special requirements must be placed on TPE raw materials, equipment, molds, and even product design.

Custom thermoplastic TPE

Therefore, for PP overmolding, the most conventional TPE formulation can be used directly without adding additional polar modifiers.

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,

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

Transparent TPE, specifically speaking, is a thermoplastic elastomer, while TPR is translated from English, strictly called thermoplastic rubber, which is the most basic difference. TPE is generally formed by modifying SEBS base materials, while TPR is modified from SBS base materials.

Custom thermoplastic TPE

Traditional soft PVC material and TPR material, with their good environmental protection, safety, non-toxic and other characteristics, are increasingly welcomed and trusted by consumers. Every industry has its own corresponding standards; for the toy industry, it also has its own special industry standards.
