HOSTAFORM C 9021 AW XAP² ™ LS | POM | Tribological
 
Description
POM copolymer
 
Injection molding type like C 9021, with special additive modified; good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation; good wear properties and low coefficient of friction.
 
Reduced emission grade. Emissions according to VDA 275 < 5 mg/kg
 
Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness more than 1 mm.
 
Ranges of applications: sliding parts for window lifter.
 
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
