Are prices from Zhejiang TPR material manufacturers favorable?

A bonding layer is formed at the interface between hard and soft plastics,

Transparent TPE is used in appliance housings, handles, grips, etc., offering excellent tactile feel, anti-slip and labor-saving properties, easy coloring and processing, and a wide design space.

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

Greatly improves the overmolding adhesion between TPE soft rubber and hard plastic. False overmolding hardly involves the compatibility of the two materials; the overmolding is achieved through mechanical force, mold and product design, surface treatment, and clamping action to bond the soft and hard plastics together.

Overmolding POM onto POM. Although POM has a low melting point, only 180℃.

Thickness of TPE/TPR overmolding layer. In most overmolding applications, a wall thickness of 1.5-3.0mm ensures good adhesion. If the TPE layer is too thin, injection molding is difficult, adhesion strength is low, and feel is poor. If too thick, costs are higher and defects like shrinkage and bubbles may occur.

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

However, due to its high crystallinity, high energy is required to form a fusion layer on the overmolding surface. Also, POM's self-lubrication hinders rapid overmolding of TPE onto POM hard plastic surfaces.

During the molding of TPE materials, during the filling of the mold cavity,

Due to the high light transmittance of transparent TPE, strict surface quality requirements are necessary: no streaks, pores, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special requirements must be placed on TPE raw materials, equipment, molds, and even product design.

TPE is a classic aggregation-induced emission molecule, meaning no fluorescence in solution but strong fluorescence in solid state. Thus, transparent TPE materials have important applications in organic optoelectronics.

If the product's filling performance is poor, there will be excessive decompression, overly long filling time, unqualified filling, etc., causing quality issues.
