PTFE needle felt is a kind of fiber with extremely stable chemical properties. The material we use is mainly imported from PTFE of USA or Lenzing from Austria. The advantages of
PTFE needle felt features are as follows:
1. Operating temp. -continuous: 250 DEG C
-instant: 280 DEG C
2. Absolutely anti acid, alkali and oxidation and hardly combustible
3. The unique no aging fiber
4. Fitting for the most vicious working conditions, with extremely long durability, usually life cycle exceed 3 years
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.
