Pure
PTFE(Teflon) Fibre Braided Packing
Item No.:ZD-P1200
Description: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,It is widely used for where contamination
is not allowed.It is recommended for chemical engineering.
