Santoprene rubber is a high performance elastomer in the thermoplastic rubber family. Santoprene is recyclable, making it more environmentally friendly. The composition of Santoprene rubber is highly cross linked rubber particles mixed throughout a continuous matrix of thermoplastic material. Santoprene rubber has an incredible fluid resistance when compared to other synthetic rubber materials such as neoprene or SBR.

Central Plastics now extrudes flexible vinyl with a bio based plasticizer.

What that means is:

  • A material free of heavy metals (excluding white profiles)
  • A high renewable carbon content
  • A low carbon footprint that has up to 50% reduction in CO2 emissions and improved environmental impact versus phthalate plasticized vinyl

This also results in improved physical properties versus phthalate-based compounds

  • Low temperature properties
  • Improved thermal stability
  • Dynamic color hold
  • Outdoor weatherability
