Description
Chemical abbreviation according to ISO 1043-1: POM
Molding compound ISO 9988- POM-K, M-GS2, 02-003, GF20
 
POM copolymer
Injection molding type, reinforced with ca 20% glass fibers; includes PTFE for improved wear performance; high resistance to thermal and oxidative degradation; reduced thermal expansion and shrinkage.
 
Ranges of applications: For molded parts requiring improved low wear performance while exhibiting very high strength and rigidity as well as higher hardness.
 
FMVSS = Federal Motor Vehicle Safety Standard (USA)
 
Other Processing
Injection Molding
Standard injection moulding machines with three phase (15 to 25 D) plasticating screws will fit.

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
