Description: PTFE needle felt is a filter material made of PTFE ( polytetrafluoroethylene fiber ) three-dimensional acupuncture. PTFE fiber is a macromolecular linear structure. PTFE needle felt has strong temperature resistance, wear resistance, corrosion resistance and chemical stability. It is widely used in various harsh flue gas filtration environments such as steel, electric power and waste incineration.

Product performance: made of 100 % pure PTFE ; applicable temperature -210 °C to 265 °C ; acid and alkali resistance, corrosion resistance, strong chemical stability ( 0-14PH ); high humidity environment is also suitable; not easy to aging; no pollution; Fabric composition: PTFE staple fiber ( PTFE  crimped fiber blended with other fibers to reduce cost and maintain a certain non-stickiness. The appearance is pure white. The content is 100 % polytetrafluoroethylene ( PTFE ). The processing is larger per square centimeter. 62 needles, antistatic agent, all steel equipment, and grounding device must be used.) +100 % PTFE base fabric ( woven with 500dtex filament fiber (monofilament), fabric is plain weave. PTFE fabric can be based on filter strength requirements of different design, such as warp and weft density: warp 140 root / 10cm, weft 140 root / 10cm (140 / m ) , the base fabric may be warp and weft strength greater than 1000NBased on the chemical stability of PTFE raw materials, it is the most chemically resistant and stable product of all filter materials.

1. The continuous working temperature is above 250 degrees and the instantaneous temperature is 280 degrees.

2 , completely afraid of acid and alkali and oxidation, almost non-combustible.

3 , the only fiber that does not age.

4 , to meet the most severe working conditions, has an extremely long service life, usually a service life of more than 4 years.
