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. Improved electrical conductivity.Properties:no microporosityhigh strengthhigh rigidityhigh thermal stabilitylow water absorptionhigh dimension stabilitygood electrical insulating propertiesvery good sliding propertieshigh resistance to stress cracksnot resistant to high concentrated acidsdifficult to glue and paintApplications include bearings, fittings, gear wheels, parts for pumps, screws, bobbins, parts for textile industry, and medium for coating lines.
