What is PPS (Ryton) Needle Felt Filter Fabrics?

PPS (Ryton) needle felt filter fabrics are made out of PPS (Polyphenylene Sulfide) fiber, special for high-temperature baghouse filter bags. The PPS (Polyphenylene Sulfide) fiber is a high-performance fiber. It has excellent characteristics such as high-temperature resistance, hydrolysis resistance, acid and alkali resistance, abrasion resistance, flame retardancy, and good mechanical strength. 

Outstanding Advantages of PPS (Ryton) Needle Felt Filter Fabrics

  • High-temperature resistance, good thermal stability, continuous working temperature < 190℃, instantaneous working temperature 200℃, melting point is 285℃. 170 ~ 190 ℃ is the best working temperature of PPS needle felt filter media. Under 190 ℃, the breaking strength in warp and weft securely decrease.
  • Good hydrolysis resistance only decomposes in strong oxidants.
  • Excellent acid and alkali corrosion resistance, only after the PTFE (polytetrafluoroethylene).
  • Excellent corrosion resistance, it’s good resistant to organic acids, inorganic acids, oxidants, etc.
  • Excellent flame retardancy, LOI (Limited Oxygen Index) of PPS is 34, it’s a good flame retardant filter fabric.

Main Application of PPS (Ryton) Needle Felt Filter Fabrics:

  • Coal – Fired Boilers baghouses
  • Municipal Solid Waste Boilers
  • Waste incinerator
  • Calciners / Catalysts
  • Electric power plant
  • Iron and nonferrous Metal Industry
