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.It’s widely used in sealing of food equipment,chemical industry,sealing of high linear velocity valve or pump.So there are many kinds of PTFE sealing material which are made from PTFE fibre.PTFE sealing material/Teflon sealing material are including:Pure PTFE yarn,PTFE Graphite Yarn,PTFE Tape,reformative PTFE sheet,PTFE rods,PTFE sheet,PTFE gasket,teflon yarn,teflon tape,teflon graphite sheet,teflon sheet,EXPANDED PTFE JOINT SEALANT,EXPANDED PTFE VALVE STEM PACKING,PTFE thread tape,ect.
