Hostaform C 2521 G Ticona Acetal (POM) Copolymer

Product Description

Chemical abbreviation according to ISO 1043-1: POM
Molding compound ISO 9988- POM-K, M-GNS, 01-001

POM copolymer

Stiff-flowing type for injection molding and extrusion, modified
with (R) GUR (PE-UHMW) good chemical resistance to solvents, fuel
and strong alkalis as well as good hydrolysis resistance high
resistance to thermal and oxidative degradation with GUR (PE-UHMW)
modified extrusion type, therefore very good lubricating properties.

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

Ranges of applications: For injection molding parts and
semi-finished products with higher requirements on lubricating
properties.

FMVSS = Federal Motor Vehicle Safety Standard (USA)
