Chemical abbreviation according to ISO 1043-1: POM
Molding compound ISO 9988- POM-K, M-GNR, 05-002, GB30

POM copolymer

With 30 % glass spheres reinforced, very easy flowing injection
molding type; low-warpage; high resistance to thermal and oxidative
degradation.

Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness
more than 1 mm.

Ranges of applications: low-warpage and dimensionally stable molded
parts with higher rigidity and hardness.

FMVSS = Federal Motor Vehicle Safety Standard (USA)
