Product Description

Polyoxymethylene sheet and rod is extruded by POM material under high temperature.  It is with high melting point and high crystallinity. Due to POM with excellent performance, it is very suitable for auto lathe machine to reprocess.  It could be reprocessed to precision parts perfectly.  POM is with high mechanical strength, rigidity, high hardness, good elasticity, good slip and abrasion resistance. Even under low temperature, it is also with high impact resistance, excellent dimensional stability, mechanical properties, and physical inertial, suitable to contact with good.  
     It is widely used in Auto, electronic, clothing, medical, machinery  and sports equipments as sliding parts, precision parts, gears , bearings etc.
