Hostaform® C 2521 LS
聚甲醛(POM)共聚物
Celanese Corporation
产品说明:
POM copolymer
Stiff-flowing type for injection molding and extrusion with high impact toughness and good tracking resistance over a high range of temperature; good chemical resistance to solvents, fuel and strong
alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation.
This grade has been specially stabilized to prevent discoloration and deterioration of mechanical properties from ultraviolet light exposure.
The material is available in natural, black and colored.
Burning rate ISO 3795 and FMVSS 302 < 75 mm/min for a thickness more
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)
