POM C 9021 SW XAP LS 减声器,低摩擦,经润滑,耐磨损
HOSTAFORM C 9021 SW XAP² ™ LS | POM | Tribological
Description
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
