PTFE
fiber packing is pure PTFE fiber yam packing braided
into square cross section and impregnated with PTFE
dispersion. High cross-sectional density and structural
strength. Inert to almost all chemicals and has great
resistance to mechanical attack. Low
coefficient
of friction results in easy shaft running. Long service
duration is ensured as PTFE yarns are stable and there
is no lubricant squeezed out under operating pressure.
