Product description

Description

We all know that PTFE 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 fibre 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.

Application  

It’s widely used in sealing of food equipment,chemical industry,sealing of high linear velocity valve or pump. Specially, PTFE fibre braided packing can be applied to seal all chemicals except molten alkali metal because PTFE fibre has perfect resistance to most of chemicals. PTFE fiber braided packing can be used to seals of pharmaceutic . General speaking,it is widely used for where contamination is not allowed. It is recommended for chemical engineering.
