  • Flame retardant
  • High strength & stiffness
  • Excellent dimensional stability
  • Lubricated
  • High heat resistance
  • Broad temperature range capability
  • Good creep strength
  • Good resistance to hydrolysis and steam
  • High mechanical strength
  • Good insulating and dielectric properties
  • Semi-transparent
  • Typically has an amber tint
  • Food grade variations available
  • Not UV resistant and poor weatherability  – unsuitable for outdoor applications
