TPV successfully combines some of the characteristics of vulcanized rubber, such as heat resistance and low compression set performance, with the easy processing characteristics of thermoplastics. It has excellent dynamic fatigue resistance, high tear resistance, and excellent weather resistance. , Good abrasion resistance, excellent hydrolysis resistance and grease performance, can be used in the range of -40℃～150℃. EPDM/PP type thermoplastic dynamic vulcanized rubber (TPV) has environmental resistance equivalent to general-purpose EPDM materials, and its oil and solvent resistance is comparable to general-purpose neoprene. This unique combination of excellent environmental resistance makes this thermoplastic rubber suitable for a wide range of uses. The performance of EPDM/PP type thermoplastic dynamic vulcanized rubber (TPV) is similar to that of many common vulcanized special rubbers. These characteristics provide product designers and material engineers with the opportunity to use lower-cost thermoplastic processing methods without affecting the desired product.
TPV performance characteristics:
The performance characteristics of EPDM/PP type thermoplastic dynamic vulcanized rubber (TPV) include the following aspects:
1. The touch of rubber and the processing method of plastic.
2. It has mechanical properties within the effective operating range of -40°C to +150°C.
3. For water-based liquids, oils and hydrocarbons, it has chloroprene-grade oil and solvent resistance.
4. Small compression deformation and permanent deformation.
5. Exposure at 150°C for two weeks or longer at 125°C shows its excellent heat-resistant air aging performance.
6. Excellent anti-dynamic fatigue performance.
7. Very high tear strength.
8. Excellent ozone and weather resistance
9. It has excellent adhesion with polypropylene (PP) or nylon (PA).
The good combination of oil resistance and environmental resistance makes TPV suitable for a wide range of applications. The performance of TPV is similar to that of common vulcanized special rubber. It is processed by a lower-cost thermoplastic molding method to achieve the same processing effect and economy as thermoplastic materials. The clean waste generated during the molding process can be recycled.
