Advantages of Shanghai Rubber TPE Suppliers

TPE is processed using overmolding injection bonding technology,

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

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

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 overmolding injection bonding generally uses a two-shot injection molding process, where the molded rigid plastic part is fixed in the overmolding mold,

Since any impurities in the TPE material can affect product transparency, sealing must be ensured during storage, transportation, and feeding to keep the TPE raw material clean. Especially if the TPE raw material contains moisture, heating can cause degradation, so it must be dried. During injection molding, a dry hopper must be used for feeding.

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

Then, at an appropriate temperature, the soft TPE is injection bonded onto the rigid plastic part, and after cooling, the product is obtained. The injection temperature for overmolding bonding varies depending on the rigid plastic material being overmolded.

For two-shot overmolding of nylon using a standard injection molding machine, it is recommended before overmolding

Because transparent TPE material requires high light transmittance, strict surface quality is necessary. There must be no defects such as streaks, pores, whitening, haze, black spots, discoloration, poor gloss, etc. Therefore, throughout the injection molding process, strict and even special requirements must be paid to TPE raw materials, equipment, molds, and even product design.

Transparent TPE is specifically a thermoplastic elastomer, while TPR is translated from English and strictly speaking is called thermoplastic rubber. That is the most basic difference. TPE is generally modified and shaped from the base material SEBS, while TPR is modified from SBS.

First, preheat and bake the nylon part because nylon has strong water absorption and overmolding requires higher molding temperature; preheating before overmolding removes moisture and facilitates rapid hot overmolding.
