Celcon® M90SW
POM(聚甲醛)
塞拉尼斯(Celanese)
产品描述
Low wear, low noise for high load, low speed applications.
Celcon M90SW is a low wear grade designed for gears and other low wear applications, especially where reducing noise and wear against the same mating surface is important. This grade may be preferred in high load-low velocity applications. Celcon® M90SW is an option where silicone or PTFE based wear resistant products are not acceptable. Please also see Hostaform® C 9021 SW.
