Features & Benefits

Main Characteristics

Copolymers offer better abrasion resistance and chemical / thermal properties. Homopolymers, being more crystalline, exhibit greater mechanical resistance and superior hardness.

  • Good electric insulation and dielectric characteristics.
  • Low humidity absorption and availability of FDA compliant variants.
  • Excellent dimensional stability and easy machining.
  • Excellent mechanical resistance and rigidity.
  • High toughness
  • Good machinability
  • High strength
  • Resistant against cleaning agents
  • Good slide and wear resistance
