PTFE
fiber is a kind of synthetic fiber, made by spinning or slicing after making
films, or fibrillating. PTFE fiber can be used with a range from -200℃ to 260℃, and it has the same
properties as PTFE, e.g. corrosive resistance, low friction, chemical stability, climate-resistance, creep-resistance, anti-oxidant
and non-physiological toxicity. It will not burn, melt, or contaminate the
filtered media, and it can even be recycled. It is mainly used as filter bags
of high temperature dust, highly corrosive -resistant
filter materials to filter gas or liquid, the filler of pump and valve, seal
tape, self-lubricant bearing, strengthening materials for perfluorinated ion
exchange membrane, and felt cloth on the rocket-launching pad.
