Benefits of Beijing Secondary Molding TPR

TPE uses overmolding injection bonding process, commonly used products such as 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.

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

The material gives the product a comfortable touch, improves grip, enhances product aesthetics and added value.

With the rapid development of the TPE elastomer industry in recent years,

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.

Olefin transparent TPE has good weather resistance and ozone resistance, so it is called the fastest growing variety of TPE. It mainly serves as a major rubber material in fields such as automotive and home appliances.

Secondary Molding TPR

The application of TPE overmolding secondary injection molding is becoming more mature. Many hard plastic products, after introducing soft TPE elastomer material, have improved touch, grip, aesthetics and other functional properties.

TPE material has good fluidity, mainly for injection molding.

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, etc. for producing transparent TPE, and also promotes excellent properties such as high temperature resistance and corrosion resistance. This is how transparent TPE is made.

To prevent contamination of TPE raw materials and the presence of old material or impurities in the screw and accessory recesses, especially for materials with poor thermal stability, it is necessary to use screw cleaner to clean all parts before use and after shutdown, so that no impurities adhere.

TPE semi-finished toy products can be used for spray painting (spray paint, inkjet), screen printing and other post-processing. Our company produces and sells TPE soft rubber materials, which can be used for injection molding to produce soft toys, simulated animal toys, plant toys, fruit toys, etc. The TPR provided has excellent color matching and oil spray properties, environmentally friendly and non-toxic. Next, let's see what surprises TPE toy manufacturers have brought us.
