PTFE has a coefficient of friction
that is one of the lowest of any material ,between 0.05 and 0.09 .PTFE also is
extremely corrosion resistant ,especially to acids ,harsh inorganic and organic
chemicals ,it is attacked only by the alkaline metals in the elementary state ,by
Chlorine trifluoride and by elementary Fluorine at high temperature and
pressures .In addition ,PTFE can withstand a wide of temperatures ,from +260℃ down
to -180℃ .
The extraordinary characteristics of
PTFE makes it the ideal choice in a wide range of applications ,such as
chemicals ,petrochemicals ,fertilizers ,agrochemicals ,dyestuff ,textile ,paper ,clothing ,building ,food
processing plants and valves industries.
PTFE rod (Bar) is made from 100% virgin ptfe pre-sintered resin ,it has two kinds of rods according to production method .One is
