1.PTFE needle felt for chemical industry
2.excellent PTFE filter cloth
3.100% pure high-performance filter fabric cloth

PTFE needle  felt has extremely stable chemical properties.

The advantages of PTFE needle filter felt fabric are bellowed:
1. operating temp. -continuous: 250 DEG C
operating temp. -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 more than 4 years
100% PTFE needle felt media is mainly used in the fields of chemical industries, waste incinerator, and high temperature liquid filtration. PTFE can maintain excellent chemical stability under different working conditions while because of the high expense, PTFE needle felt are  not usually widely used.
