SF-1S is of oil resistant,acid resistant,alkali resistant and seawater resistant,more over,there is no lead in the PTFE surface layer and so is particularly fit for application in food machinery,alkali flow meters,pumps motion elements in pharmaceutical machines,printing machines chemical engineering machines and other ocean industry.The bushing is a triple layers composites one,the base material is stainless steel back and a film of heat resistant power filled PTFE being calendered onto the sintered spherical bronze interlayer.
