Fengxinyuan PTFE needle felt

  It is a kind of fiber with extremely stable chemical properties
The fiber is mainly imported from Teflon of the United States and inspec of Austria
Its characteristics are as follows: 1
The continuous working temperature is more than 250 degrees and the instantaneous temperature is 280 degrees
2
Completely afraid of acid and alkali and oxidation, it is almost nonflammable
3
The only fiber that won't age
4
It meets the worst working conditions and has a very long service life, usually more than 4 years
100% PTFE needle felt filter material is mainly used in chemical industry, waste incineration, high temperature resistant liquid filtration, etc
it maintains good chemical stability under various complex working conditions, but it is not suitable for wide use because of its high price; Product Name: TF / TF a750bsg fiber , Dimension 100% PTFE base , Cloth 100% PTFE square gram weight 750g / m2 thickness , 1
