Description
Chemical abbreviation according to ISO 1043-1: POM
Molding compound ISO 9988- POM-K, M-GNS, 02-002, K10
 
POM copolymer
 
Injection molding type, special modified with anti-friction additives  for prevention of squeaking noise; good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation.
 
UL-registration in natural and black and a thickness more than 1.5 mm as UL 94 HB.
 
Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness more than 1,5 mm.
 
Ranges of applications:  For sliding combinations with low wear and low coefficient of friction, prevents squeaking noise.
 
UL    = Underwriters Laboratories (USA)
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
