Custom Resins Group
產(chǎn)品說明:
Durab MF3 is a high-viscosity acetal co-polymer. Durab MF3 has slightly higher toughness than standard MF9, and parts molded with MF3 should have thicker wall sections and shorter flow lengths to accommodate the higher viscosity. MF3 is suitable for such applications as clips, fasteners, gears, bushings and bearings, and other uses where long term creep and wear resistance are required.
