产品说明

AH50F20 is an acetal homopolymer composition containing 20% of a specially selected fluoropolymer, finely dispersed throughout the base resin. It is suitable for processing by injection molding.

Although acetal homopolymer exhibits exceptional bearing characteristics, including a very low coefficient of friction, the incorporation of this fluoropolymer minimizes "stick/slip" behavior and substantially enhances PV capabilities throughout a wide range of pressure/velocity combinations, but in particular for higher load/lower speed applications.

AH50F20 processes easily and offers opportunities to attain fast cycle time. This composition should be considered for applications where the outstanding dimensional stability, and chemical, oil and solvent resistance, that are typical of acetal homopolymer are required, in combination with excellent low friction and wear characteristics, particularly where the use of externally applied lubricants is not acceptable.
