TPE, also known as thermoplastic elastomer, not only has high strength, high elasticity and high resilience of rubber, but also has the characteristics of plastic processing. TPE is widely used in various fields for its excellent coloring, weather resistance, soft touch, fatigue resistance and temperature resistance. Do you know the main components of TPE materials?
Composition of TPE material:
1、SEBS、SBS
The unit price of SEBS will be higher than that of SBS formula. However, TPE made by SEBS has many advantages.
2、PP
The MFR of PP is an important index for selecting PP. If the melt index is too low, the plasticization will be obviously affected, and the surface of products will be uneven and have bumps. From experience, the price of powder PP is lower than that of pellet PP, and its dispersibility is better, so it is the main raw material used by many TPE raw material manufacturers.
3. Rubber oil
Rubber oil is an item that can improve the elasticity, flexibility, easy processing and easy mixing of rubber.
4. Calcium carbonate
White powder or colorless crystal. No smell. Tasteless.
TPE is a polymer composed of many kinds of materials, the main substrates are SEBS, SBS, rubber oil,
