White anti-static POM wear-resistant steel plate General Engineering Plastics
The fatigue strength of POM is very outstanding. After 10 alternating loads, the fatigue strength can be reached, while PA and PC are only. The creep property of POM is similar to that of PA, only 2.3% at 20℃, and it is not affected by temperature.
POM has a small friction factor and good wear resistance (POM>>PA6>ABS>HPVC>PS>PC), a large limit PV value, and good self-lubricity. POM products are prone to squeal-like noise when they are subjected to high load.
