Specification:
PTFE fiber packing is a pure yarn 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.
