Chemical abbreviation according to ISO 1043-1: POM Molding compound ISO 9988- POM-K, M-GNS, 01-001 POM copolymer Stiff-flowing type for injection molding and extrusion, modified with (R) GUR (PE-UHMW); good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation; with GUR (PE-UHMW) modified extrusion type, therefore very good lubricating properties. Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness more than 1 mm. Ranges of applications: For injection molding parts and semi-finished products with higher requirements on lubricating properties. FMVSS = Federal Motor Vehicle Safety Standard (USA) |
