Molding compound ISO 9988- POM-K, M-GNS, 02-002, K10
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.
UL-registration in natural and black and a thickness more than
1.5 mm as UL 94 HB.
Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness
more than 1,5 mm.
Ranges of applications: For sliding combinations with low wear and
low coefficient of friction, prevents squeaking noise.
UL = Underwriters Laboratories (USA)
FMVSS = Federal Motor Vehicle Safety Standard (USA)
