How to choose a transparent TPE manufacturer in Jiangsu

TPE adopts overmolding injection process,

To prevent contamination of TPE raw materials and old materials or impurities in the screw and attachment recesses, especially materials with poor thermal stability, before use and after shutdown, the screw cleaning agent should be used to clean all parts thoroughly, ensuring no impurities adhere.

Transparent TPE, specifically speaking, is thermoplastic elastomer, while TPR is translated from English, strictly called thermoplastic rubber, which is the most basic difference. TPE is generally formed by modifying the basic material SEBS, while TPR is modified from the basic material SBS.

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

With the rapid development of the TPE elastomer industry in recent years,

Transparent TPE is used in home appliance shells, handles and grips, etc. It exhibits very good hand feel, has anti-slip and labor-saving properties, and is easy to color and process. It also has a wide design space.

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

The application of TPE overmolding secondary injection molding is becoming more and more mature. Many hard plastic products, after introducing the soft elastomer TPE material, improve the product's touch, grip, aesthetics and other functional features.

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

The thickness of the TPE and 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 hand 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 are likely to occur.

Since any impurity in the TPE material may affect the transparency of the product, sealing must be ensured during storage, transportation, and feeding processes to keep the TPE raw material clean. Especially if the TPE raw material contains moisture, heating will cause the material to deteriorate, so drying is necessary. During injection molding, a drying hopper must be used for feeding.

Common rigid materials used in cooperation are mainly plastics, as well as metals and fabrics. TPE injection over fabric is mainly used in luggage products. Like metal overmolding, it is generally false overmolding. True overmolding is more common in secondary injection molding and two-color injection molding, that is, the main material of TPE overmolding injection is plastic.
