POM C 2521 G 抗溶解,耐化学,耐油
HOSTAFORM® C 2521 G
HOSTAFORM C 2521 G | POM | Tribological
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)

Processing
Pre Drying
Necessary low maximum residual moisture content: 0.15%
Drying is not normally required. If material has come in contact with moisture through improper storage or handling or through regrind use, drying may be necessary to prevent splay and odor problems.
The product can then be stored in standard conditions until processed.
Drying time (h)：3 - 4
Drying temperature (℃)：100 - 120
