SF-1S 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 bushings in foodstuff machines, alkali flow
meters, pumps motion elements in pharmaceutical
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.
