What is TPV?
TPV (Thermoplastic Vulcanizate) is made of polymer(PP/PE/PS) and rubber (EPDM, NBR, SEBS, ACM, etc ) with oil, plasticizer, additives, etc.
TPV Properties
- Good elasticity
- Compression deformability resistance
- Anti-Aging
- Wide temperature adaptability, could be used under temperatures -60 C to 135 C
- Good process properties
- Recyclable
- Low bulk density (0.9-0.97)
- Hardness between Shore 25A to Shore 65D
Applications
It is widely used in Automotive, Electrics, Consumer tools, transport tools, construction tools, etc
Main components to get TPV
- Gravimetric feeding system
- High torque twin screw compounder
- Vacuum system
- Melt pump
- Under water pelletizer
