POM Sheet with Good Wear Resistance

Description
POM is a kind of engineering plastic with good mechanical properties. POM together with UHMW PE,Nylon,PTFE are known as four most abrasion resistant plastics. It has almost the same rigidity as metal, so it's an ideal replacement material of copper, cast zinc, steel, aluminum and other metal materials. We are able to produce POM products without bubbles or cracks. 

Characteristics
-High surface hardness
-Good wear resistance
-Excellent machinability
-Nice self-lubricating properties
-Good dimensional stability
-Low water absorption
-Oil resistant
-Work under the temperature of -40-100℃
