About raw material:

PTFE needle felt is a kind of fiber with extremely stable chemical properties. The material we use is mainly imported from Teflon of USA or Lenzing from Austria.

The advantages :

1. Fitting for the most vicious working conditions, with extremely long durability, usually life cycle exceed 3 years

2. Absolutely anti acid, alkali and oxidation and hardly combustible

3. Operating temp. continuous: 250 DEG C ; instant: 280 DEG

4.The only fiber which won’t ageing

Wide application:

Because of the excellent stable chemical properties under different complicated working conditions, the 100% PTFE needle felt media is usually used in the fields of chemical, waste incinerator, high temperature liquid filtration and so on.
