Milastomer™ is a Thermoplastic Vulcanizate (TPV) ,derived from olefin-based rubber and polyolefin resin. MILASTOMER™ TPVs offer the sustainability benefits of a polyolefin with the durability and flexibility of a vulcanized rubber. Produced with the olefin polymerization and synthetic rubber technology of Mitsui Chemicals, MILASTOMER™ does not require compounding or vulcanization. It is a thermoplastic resin that can be extruded, or molded into flexible parts. MILASTOMER™ is available in standard black, or in natural grades that can be easily colored.

MILASTOMER™ key performance benefits:

  • Light Weight – density less than 900 kg/m3.
  • Heat Resistance – Higher softening temperature than other Elastomers.
  • Rubber Elasticity – Deformation recovery superior to vulcanized rubber in long-term compression set.
  • Weatherability – MILASTOMER™ B (black) grades may be used outdoors over the long-term. Both black and natural grades have superior ozone resistance.

Applications :

  • Automotive parts
  • Building materials
  • Appliance parts
  • Sporting goods
