  • Material: 100% PPS fibers (often known by brand names like Ryton®)
  • Weight Range (GSM): 450–600 g/m²
  • Operating Temperature: Continuous: 160°C | Peak: 190°C
  • Resistance:
    • Hydrolysis: Excellent
    • Acids: Excellent
    • Alkalis: Excellent

  • Typical Applications: Coal-fired boilers, waste-to-energy plants, incinerators, and chemical filtration in high-sulfur or acidic gas streams.

Description & Usage

PPS filter bags are the premium choice for harsh, high-temperature environments where chemical resistance is critical. They are exceptionally stable in the presence of acids and alkalis and possess excellent hydrolytic stability, making them ideal for “wet” high-temp applications. Their primary use is in coal-fired power station filtration where sulfur content in the fuel creates a highly corrosive flue gas that would degrade other fibers.
