Which TPR for secondary molding in Henan is good?

TPE overmolding generally uses a two-shot injection molding process,

SEBS is the product after hydrogenation of SBS. SEBS has a saturated molecular structure, which leads to very different characteristics. It has the necessary aging resistance, yellowing resistance and other properties for producing transparent TPE, and also contributes to excellent high temperature resistance and corrosion resistance. That is how transparent TPE is made.

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, all parts should be cleaned with screw cleaner before use and after shutdown to ensure no impurities adhere.

Secondary molding TPR

Fix the rigid plastic parts that have been injection molded onto the overmolding mold, then at a suitable temperature inject TPE soft material to bond to the rigid parts. After cooling, the product is obtained. The injection temperature for overmolding depends on the hard plastic material being overmolded.

TPE is processed by overmolding. Common products include handles, grips, electronic materials, etc.

Transparent TPE is used in appliance housings, handles, grips, etc. It provides very good touch, anti-slip and labor-saving properties, and is easy to color and process. It also has a wide design space.

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

Secondary molding TPR

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 as a raw material. TPE material manufacturers are environmentally friendly, non-toxic, elastic, and have a smooth surface. In addition,

Transparent TPE material has different product properties when applied in different aspects. Thermoplastic elastomer is also called TPE material. Transparent TPE not only has the processing performance of thermoplastic plastics, but also has the physical properties of vulcanized rubber. This is the advantageous combination of plastic and rubber. Transparent TPE is widely used in people's life and production.

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

Secondary molding TPR

The surface is not easy to attract dust, has good thermal conductivity, excellent anti-fouling performance. Through skin safety and non-sensitization tests, it meets the characteristics that silicone cannot, making the appearance more high-end and exquisite. The TPE industry positions it as the preferred raw material for high-end applications.
