Description

Hostaform®/Celcon® is a family of acetal copolymers (POM), developed by Celanese Corporation, which offers a wide range of high mechanical properties due to its linear structure and highly crystalline quality. These properties include excellent wear and creep resistance, high toughness, and long-term fatigue strength. It is also resistant to moisture, strong alkalis and solvents.
Hostaform® M90 XAP® grade is an acetal copolymer with low emissions and medium viscosity that provides top-notch performance in processes such as injection moulding in areas such as the automotive industry, particularly the interior automotive market. It is generally delivered in pellets. Key features of Hostaform® M90 XAP® include:

  • High toughness (to - 40°C)
  • High hardness and rigidity
  • Outstanding chemical resistance
  • Good wear resistance and sliding properties
  • Easy colorisation
  • Good heat distortion temperature (up to 100°C)
  • Excellent resilience
  • Low moisture absorption
  • Resistance to stress cracking
