What is the difference between polyoxymethylene, nylon and ultra high molecular weight polyethylene?


POM


Material quality, its dimensional stability is much higher than nylon, ultra high molecular weight polyethylene, its mechanical strength is higher than nylon and ultra high molecular weight polyethylene, but the wear resistance is slightly worse, but its outstanding mechanical strength and dimensional stability characteristics It is widely used, and is used for precision mechanical parts such as bushings and cylinder guide bushings.


Nylon


Wide range of materials, can be subdivided into nylon 6, nylon 66, nylon 10, nylon 1010, nylon 46, MC nylon, oily nylon, etc., wear resistance is outstanding, 80% of the market's gears are made of nylon, its toughness is very High, mechanical strength will not be reduced, can withstand impact, high pressure, high load, crane wire pulley, heavy truck pulley, etc. use nylon material, its shortcoming is not resistant to acid and alkali, easy to degrade when exposed to acid and alkali, water The rear size will also vary slightly.


Ultra high molecular weight polyethylene


Material, its molecular weight can be up to 8 million, wear resistance is better than nylon, but the mechanical strength is slightly lower, can be used for light load, wear resistance is higher than nylon, temperature resistance is general, heat distortion temperature is 80 degrees.
