产品说明

AH50AF is an acetal homopolymer composition containing a specially selected fibrous 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 eliminates "stick/slip" behavior and substantially enhances PV capabilities throughout a wide range of pressure/velocity combinations.

AH50AF 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, typical of acetal homopolymer are required, in combination with very low friction and wear characteristics, particularly where the use of externally applied lubricants is not acceptable.
