Chemical abbreviation according to ISO 1043-1: POM-HI
Molding compound ISO 9988- POM-K, M-GNPR, 05-001

POM copolymer, modified

Easy flowing, elastomer-containing injection molding type based on
HOSTAFORM C 27021 with high toughness, and slightly lower hardness,
rigidity and chemical resistance than the basic type; high
resistance to thermal and oxidative degradation.

UL-registration in natural and a thickness more than 1.57 mm as UL 94
HB. Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness
more than 1 mm thickness.

Ranges of applications: For thin-walled molded parts with high
energy-absorbing capacity.

UL = Underwriters Laboratories (USA)
FMVSS = Federal Motor Vehicle Safety Standard (USA)
