产品说明
AC90F05L is an acetal copolymer composition containing 5% by weight of a specially selected fluoropolymer, finely dispersed throughout the base resin. This compound offers a viscosity suitable for general purpose injection molding applications.
Although acetal copolymer is one of only a few thermoplastics to naturally exhibit excellent bearing performance, the incorporation of this fluoropolymer reduces "stick/slip" behavior, and enhances PV capabilities throughout a wide range of pressure/velocity combinations, but especially at velocities up to 100 ft./min.
Acetal copolymer exhibits an exceptional balance of properties, including high strength and rigidity, a unique resilience, outstanding static and dynamic fatigue strength, and resistance to a very wide range of solvents, oils, greases and chemicals, including strong alkalis. Retention of performance after long term high temperature exposure in air or water has been proven in a wide range of demanding applications.
This composition should be considered for applications where these characteristics, together with the outstanding dimensional stability typical of acetal polymers, are required, in combination with low friction and wear characteristics, particularly where the use of externally applied lubricants is not acceptable.
