Advantages of Zhejiang TPE Material Suppliers

In the elastomer industry, TPE generally refers to a composite functional material modified with SEBS.

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

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

TPE elastomeric soft rubber has excellent comprehensive properties and is the most commonly used soft rubber material for overmolding, insert molding, and two-color injection molding.

PP overmolding is a plastic with very weak polarity, very close to the polarity of TPE based on SEBS.

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.

Transparent TPE specifically refers to thermoplastic elastomer, while TPR, translated from English, is strictly called thermoplastic rubber. This is the basic difference. TPE is generally modified from SEBS base material, while TPR is modified from SBS base material.

Therefore, for PP overmolding, the most conventional TPE formula can be used directly without adding additional polar modifier.

Preheating the insert before overmolding helps improve bonding strength,

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

SEBS is the product of 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 required for producing transparent TPE, as well as excellent heat resistance and corrosion resistance. Only then can transparent TPE be manufactured.

Because the preheating process can improve the compatibility between the insert material and TPE. As for the appropriate temperature of the insert, it needs to be discussed and determined with the material supplier.
