Material Notes:
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 Low wear, low noise for high load, low speed applications.Standard reciprocating screw injection molding machines with a high compression screw (minimum 3:1 and preferably 4:1) and low back pressure (0.35 Mpa/50 PSI) are favored. Using a low compression screw (I.E. general purpose 2:1 compression ratio) can resuInformation provided by Celanese
