Acetal Copolymer (Tradename: Ertacetal C)

Acetal Copolymer is more resistant against hydrolysis, strong alkalis and thermal-oxidative degradation, and offers slightly improved chemical resistance than our homopolymer acetal Delrin grade.

Our acetal copolymer is the only porosity free acetal product available today and is FDA compliant (when purchased in white rod, sheet and tube or black rod and tube).

Example applications using our copolymer acetal rod and acetal sheet are:
  • Gear wheels with small modulus
  • Cams
  • Bearings and gears with small clearances
  • Heavily loaded bearings and rollers
  • Snapfit assemblies
  • Dimensionally stable precision parts
  • Valve seats
  • Electrically insulating components
