As we know,PTFE fiber has perfect resistance to most of chemicals except molten alkali metals.This kind of plastic has perfect self-lubricant. PTFE is called "king of plastic".And the PTFE cause no pollution to the medium or liquid.Pure PTFE fiber braided packing is a braided packing made of PTFE yarn without soaking any PTFE dispersion and lubrication. But PTFE fiber braided packing has greatly enhanced ability to seal high speed shafts with the addition of inactive and heat-resisting agents.It's widely used in sealing of food equipment,chemical industry,sealing of high linear velocity valve or pump.Specially,PTFE Fiber Braided Packing can be applied to seal all chemicals except molten alkali metals because PTFE fiber has perfect resistance to most of chemicals.PTFE fiber braided packing can be used to seals of pharmaceutic.Generall speaking,PTFE fiber braided packing is used for where contamination is not allowed.It is recommended for chemical engineering.We can also add some other material or improve the process of braiding to enhance the capability of PTFE packing.We have PTFE GRAPHITE PACKING ARAMIDE CORNERS,PTFE Filament Packing,PTFE PACKING WITH LUBRICANT,MULTIPLE PTFE FILAMENT PACKING,PTFE graphite fibre packing,PTFE Packing with silicone rubber core,ect.
