PPS/PTFE High-Temperature Chemical Fiber Needle Punched Filter Material (Corrosion-Resistant for Flue Gas Filtration)
Products Description
Performance and characteristics:
PPS Series: Made of polyphenylene sulfide fibers, stable at ≤190℃ (continuous) with strong chemical resistance-ideal for flue gas filtration in high-sulfur environments (power plants, waste incineration).
PTFE Series: Crafted from polytetrafluoroethylene fibers, resistant to ≤260℃ (continuous) and extreme corrosion-suitable for harsh flue gas filtration scenarios (steel, chemical industries).
