Are Jiangxi Natural Color TPE Suppliers Reliable?

TPE uses overmolding injection processing. Common products include handles, grips, electronic materials, etc.

Transparent TPE is used in stationery, sports equipment, etc. It has good UV resistance, chemical resistance, and is easy to color and process.

Diene transparent TPE, diene 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 shoemaking, sponge, optical film, and other industrial rubber products due to its good transparency, weather resistance, electrical insulation, and photodegradability.

The material gives the product 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 overmolding, as the name suggests, is overmolding TPE soft material onto other materials.

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which leads to very different characteristics. It has the necessary aging resistance, yellowing resistance, and other traits required for producing transparent TPE, and also contributes to excellent heat resistance and corrosion resistance. Thus, transparent TPE is made.

Transparent TPE materials have different product properties in different applications. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing properties of thermoplastic plastics but also the physical properties of vulcanized rubber. This is the advantageous combination of the advantages of plastics and rubber. Transparent TPE is widely used in people's life and production.

Common processing methods include one-step molding with a two-color injection molding machine, or using a general injection molding machine with an overmolding mold in two-step injection molding. TPE overmolded products are generally handles, grips, etc. TPE soft material has a special comfortable touch. The introduction of TPE material enhances the grip and tactile feel of the product.

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

TPE transparent material requires high light transmittance, which necessarily requires strict surface quality of the product. There must be no defects such as streaks, pores, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special attention must be paid to TPE raw materials, equipment, molds, and even product design.

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

If the filling performance of the product is poor, there will be too much pressure reduction, too long filling time, unqualified filling, etc., causing quality problems.
