Hostaform® C 52021
聚甲醛（POM）共聚物
Celanese Corporation
產(chǎn)品說明:
Chemical abbreviation according to ISO 1043-1: POM
Molding compound ISO 9988- POM-K, M-GNR, 06-002
POM copolymer
Extremely easy flowing Injection molding type for very thin-walled
precision molded parts with unfavourite flow-path-wallthickness
relation; permits processing at reduced temperature and also shorter
cycle times; for mechanical lower requirements; good chemical
resistance to solvents, fuel and strong alkalis as well as good
hydrolysis resistance; high resistance to thermal and oxidative
degradation.
Monomers and additives are listed in EU-Regulation (EU) 10/2011
FDA compliant according to 21 CFR 177.2470
UL-registration in natural a thickness more than 0.81 mm, in black a
thickness more than 1.5 mm as UL 94 HB, temperature index UL 746 B
for a thickness of 1.5 mm, electrical 105°C, mechanical 90°C
Burning rate ISO 3795 and FMVSS 302 < 75 mm/min for a thickness more
than 1 mm.
Ranges of applications: For very thin-walled precision molded parts
with unfavourite flow-path-wallthickness relation; permits
processing at reduced temperature and also shorter cycle times.
FDA = Food and Drug Administration (USA)
FMVSS = Federal Motor Vehicle Safety Standard (USA)
UL = Underwriters Laboratories (USA)
