How to choose Anhui TPR material manufacturer

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

The thickness of the TPE, TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm will ensure good bonding. If the TPE layer is too thin, injection molding is difficult, bonding 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 like shrinkage, bubbles may occur.

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 has the physical properties of vulcanized rubber. This is the advantageous combination of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

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

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

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, due to its good transparency, weather resistance, electrical insulation, and photodegradability, it is widely used in shoemaking, sponges, optical films, and other industrial rubber products.

Common matching hard materials are mainly plastics, also metals and fabrics. TPE with fabric injection bonding is mainly used in luggage products. Like metal overmolding, it is generally false overmolding. True overmolding is more common in two-shot injection molding and two-color injection molding, meaning the main material of TPE overmolding injection bonding is plastic.

The overmolding temperature is generally controlled at 30-50°C, but for some highly crystalline TPE grades,

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

Because transparent TPE material requires high light transmittance, the surface quality of the product must be strict, without any defects such as streaks, pores, whitening, halos, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special requirements must be paid attention to regarding TPE raw materials, equipment, molds, and even product design.

The mold temperature can be appropriately raised to 70°C, which is beneficial for bonding and can achieve a more glossy overmolding surface.
