How to choose TPE raw material suppliers in Zhejiang

TPE is processed by overmolding (encapsulation injection bonding). Common products include handles, grips, electronic materials, etc.

Transparent grade includes transparent and translucent series, each with various hardness levels; excellent transparency; smooth and soft surface; good anti-yellowing performance, tear resistance, good tensile strength; environmentally friendly; suitable for various transparent series products.

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

The material gives products a comfortable touch, improves grip, enhances product aesthetics and added value. Most products are exported to developed countries and regions such as the United States, Japan and the European Union.

TPE is used in overmolding, with TPE soft rubber as the soft outer covering layer.

TPE transparent materials require high light transmittance, which inevitably demands strict surface quality of the products, free from any defects such as streaks, pores, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, during the entire injection molding process, strict and even special requirements must be paid to TPE raw materials, equipment, molds, and even product design.

Since any impurity in TPE material may affect product transparency, sealing must be ensured during storage, transportation, and feeding to keep TPE raw materials clean. In particular, if TPE raw materials contain moisture, heating can cause deterioration, so they must be dried. During injection molding, a drying hopper must be used for feeding.

Common matching hard materials are mainly plastics, also metals and fabrics. TPE overmolding with fabrics is mainly used in luggage products, similar to metal overmolding, generally false overmolding. True overmolding is mostly seen in two-shot injection and two-color injection, where the main material of TPE overmolding is plastic.

During the molding process of TPE material, during the filling of the mold cavity,

TPE is a classic aggregation-induced emission molecule, which 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 shoemaking industry, mostly replacing rubber; at the same time, its use in industrial rubber products such as adhesive tape and rubber sheets is also expanding.

If the product's filling performance is poor, there will be too much decompression, excessively long filling time, unqualified filling, etc., causing quality problems in the product.
