How to choose Beijing TPE transparent material manufacturer

TPE uses overmolding processing, common products such as handles, grips, electronic materials, etc.

To prevent contamination of TPE raw materials and the presence of old materials or impurities in the screw and attachment recesses, especially materials with poor thermal stability, it is necessary to clean all parts thoroughly with screw cleaner before use and after shutdown to ensure they are free of impurities.

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

The material gives the product a comfortable touch, improves grip, enhances product aesthetics and added value. Most products are exported to developed countries and regions such as the United States, Japan, and the European Union.

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

Due to the high light transmittance of TPE transparent material, strict surface quality requirements are necessary, without any defects such as streaks, pores, whitening, halos, black spots, discoloration, or poor gloss. Therefore, during the entire injection molding process, strict and even special attention must be paid to the TPE raw materials, equipment, molds, and even product design.

Transparent TPE is used in home appliance casings, handles, and grips. It exhibits very good feel, is non-slip and labor-saving, easy to color and process, and has a wide design space.

Commonly matched hard materials are mainly plastics, also metals and fabrics. TPE overmolding with fabric is mainly used in luggage products, and like metal overmolding, it is generally false overmolding. True overmolding is often seen in two-shot and bi-color injection molding, where the main material for TPE overmolding is plastic.

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

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

SEBS is the product of hydrogenation of SBS. SEBS has a saturated molecular structure, which makes its properties very different. It has the necessary aging resistance, yellowing resistance and other characteristics required for producing transparent TPE, and also contributes to excellent heat and corrosion resistance. This is how transparent TPE is made.

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