聚甲醛（POM）共聚物
Celanese Corporation
产品说明:
POM copolymer
Stiff-flowing type for injection molding and extrusion with highimpact toughness and good tracking resistance over a high range oftemperature; good chemical resistance to solvents, fuel andstrong
alkalis as well as good hydrolysis resistance; high resistance tothermal and oxidative degradation.
This grade has been specially stabilized to prevent discolorationand deterioration of mechanical properties from ultraviolet lightexposure.
The material is available in natural, black and colored.
Burning rate ISO 3795 and FMVSS 302 < 75 mm/min for a thicknessmore
than 1 mm.
Ranges of applications: injection molding thick-walled,void-free
molded parts; extrusion e.g. for boards and pipes.
FMVSS = Federal Motor Vehicle Safety Standard (USA)
