How about Henan TPE raw material suppliers?

TPE is processed by overmolding, commonly used for products such as handles, grips, electronic materials, etc.

Due to the high light transmittance required for transparent TPE, strict surface quality requirements are necessary, with no defects such as streaks, voids, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, throughout the entire injection molding process, strict and even special attention must be paid to TPE raw materials, equipment, molds, and even product design.

Transparent TPE is used in stationery, sports equipment, etc., and has good UV resistance, chemical resistance, and easy coloring and processing characteristics.

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

PP overmolding is a plastic with very weak polarity, very close to the polarity of TPE based on SEBS.

The wall thickness of the TPE overmolding area should be as uniform as possible to achieve the best molding cycle. Transitions between different wall thicknesses should be gradual to reduce problems caused by fluid flow, such as gas lines and bubbles.

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

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

Overmolding temperature is generally controlled at 30-50°C, but for some TPE grades with strong crystallinity,

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

Transparent TPE materials have different product properties when applied in different areas. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing properties of thermoplastics but also the physical properties of vulcanized rubber. This is the so-called advantage combination of plastic and rubber. Transparent TPE is widely used in people's daily life and production.

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