PPS (Polyphenylene Sulfide) trade names include – Fortron®, Torcon®, and Ryton®.

rytonA manufactured yarn composed of polymers containing Polyphenylene Sulfide (PPS). This fiber has high temperature resistance (230°C) and good chemical resistance.

PPS properties include:
  • Heat resistant
  • Chemical resistant
  • Vapor heat resistant
  • Insulation
  • Low dielectric constant
Sample PPS applications include:
  • Bag filtration applications
  • Liquid chemical filtration
  • Webbing used in highly toxic environments.
  • Use in acidic environments
  • Electric insulating materials
