Hostaform® C 9021 SW XAP² ™ LS
Acetal (POM) Copolymer
Celanese Corporation
产品说明:
POM copolymer
Injection molding type, special modified with anti-friction
additives for prevention of squeaking noise; good chemical
resistance to solvents, fuel and strong alkalis as well as good
hydrolysis resistance; high resistance to thermal and oxidative
degradation.
Ranges of applications: For sliding combinations with low wear and
low coefficient of friction, prevents squeaking noise.
Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness
more than 1,5 mm.
Reduced emission grade. Emissions according to VDA 275 < 5 mg/kg
