PTFE packing PTFE resin by processing with a special, then woven into a square cross-section of the filler for packing, non-impregnated PTFE emulsion, there is no lubricant grease, so does not contain other additives, which are widely used in chemical industry (in addition to gaseous fluorine and alkali metal things), pharmaceutical, food, papermaking, chemical fiber industry, has good chemical stability.

       Because PTFE has a good self-lubricating and non-viscous, so PTFE packing, not only has good flexibility, elasticity, but also has excellent corrosion resistance, it is almost all of the chemical media capability. Applied to petroleum, chemical, food, pharmaceutical, electric power and other industrial equipment installation flanges, pumps, valves seals.

       In the packing of the SMIC to enter the high flexibility of the silicone rubber (silicon sponge) for the core section, has excellent flexibility, high compression rate and rebound rate.
