TPV Twin Screw Compounding Line

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


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
