GEHR Plastics POM-C Acetal
Categories:	Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM)
Material Notes:	Polyoxymethylene can be used in temperatures up to 100°C. The high surface strength is only surpassed by a few materials. POM shows good sliding properties and high resistance to wear and tear because of the high strength and smooth surface. There is a very low risk of stress cracks. POM-C exhibits a high thermal stability and a high resistance to chemicals. Properties: no microporosity high strength high rigidity high thermal stability low water absorption high dimension stability good electrical insulating properties very good sliding properties high resistance to stress cracks not resistant to high concentrated acids difficult to glue and paint Applications include bearings, fittings, gear wheels, parts for pumps, screws, bobbins, parts for textile industry, and medium for coating lines.
