PTFE needle felt is a kind of filter media which is made of 100% pure PTFE (polytetrafluoroethylene fiber) through three dimensional acupuncture.
PTFE needle punched filter bag :
Its suitable temperature is from -210 to 265 degree
Strong acid and alkali resistance
Corrosion resistance, strong chemical stability (0-14PH)
It is suitable for high humidity environment.
Anti-aging and pollution-free.
Fabric composition: PTFE short fiber (100% polytetrafluoroethylene . In processing, each square centimeter is greater than 62 needles, anti-static agent and all steel equipment were used, and sure grounding devices were available. +100%PTFE scrim is made from 500dtex filament fiber (mono filament), and the fabric is plain weave.
The PTFE base cloth can design the different warp and weft density according to the requirement of the strength of the filter material. Such as: the /10cm to 140, the zonal 140 /10cm (140/ m), fabric warp and weft strength can be more than 1000N, the chemical stability of PTFE is the most best among in all filter medias.
1, the continuous working temperature is above 250 degrees, instantaneous temperature is 280 degrees.
2, acid and alkali resistance and oxidation, almost noncombustible.
3. The only fiber that is not aging.
4. It meets the worst working conditions and has a long service life, and the service life is more than 4 years.
Application: PTFE needle felt with high performance in temperature resistance, wear resistance, corrosion resistance and chemical stability. It is widely applied to all kinds of harsh flue gas filtration environment such as steel, electric power, garbage incineration and so on.
