Description

Chemical abbreviation according to ISO 1043-1: POM

Molding compound ISO 9988- POM-K, M-GNS, 03-002

 

POM copolymer

 

Injection molding type, modified with molybdenum disulphide; 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 a thickness more than 1.57 mm as UL94 HB, temperature index UL 746 B electrical 105, mechanical 90 (tensile impact) and 80 (tensile).

 

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

 

Ranges of applications:  For sliding combinations with high surface pressure and low sliding speed, only slight tendency to stick-slip.

 

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
