How to choose Henan thermoplastic TPE customization

TPE is processed by overmolding and injection bonding,

Transparent TPE materials have different product properties in different applications. Thermoplastic elastomers, also called TPE materials, not only have the processing properties of thermoplastics but also the physical properties of vulcanized rubber. This is the so-called advantageous combination of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

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

Thermoplastic TPE customization

Common products include handles, grips, electronic materials, etc. The material gives the product a comfortable touch, improves grip, enhances product aesthetics, and adds value.

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

TPE high-transparency materials have different product properties in different applications. Thermoplastic elastomers, also called TPE materials, transparent TPE not only has the processing properties of thermoplastics but also the physical properties of vulcanized rubber. This is the so-called advantageous combination of plastics and rubber. Transparent TPE is widely used in people's daily life and production.

Thickness of TPE/TPR overmolding layer. In most overmolding applications, a wall thickness range of 1.5-3.0mm ensures 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 the cost is higher, on the other hand defects such as shrinkage and bubbles may occur.

Common matching rigid materials are mainly plastics, also metals and fabrics. TPE overmolding with fabric is mainly used in luggage products, similar to metal overmolding, generally it is false overmolding. True overmolding is more common in two-shot injection and bi-color injection, where the main material for TPE overmolding is plastic.

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

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 shoe making, sponge, optical film, and other industrial rubber products.

Styrenic transparent TPE is widely used in the shoe industry, largely replacing rubber; at the same time, its use in industrial rubber products such as rubber cloth and rubber sheets is expanding.

Thermoplastic TPE customization

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