The homopolymer grade exhibits slightly higher mechanical properties, illustrated in the hardness, rigidity and creep resistance. The material also demonstrates elevated wear resistance and has a lower thermal expansion rate than acetal copolymer.

Key features

  • High mechanical strength and rigidity
  • High impact strength and creep resistance
  • Excellent dimensional stability and machinability
  • Low moisture absorption
  • Good electrical insulating and dielectric properties
  • No centreline porosity in copolymer grades
  • Suitable for food contact
