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
