It is of oil resistant acid resistant, alkali-resistant and seawater resistant. Moreover, there is no lead in the PTFE surface layer, and so is particularly fit for bushes in foodstuff machines, alkali flow meters, pumps motion elements in pharmaceutical machines, printing machines, chemical engineering machines and other ocean industry. This is a triple layers composites bush, the base material being a bronze plate and a film of heat resistant powder filled PTFE being calendered onto the sintered spherical bronze interlayer.
