PPS Needle Punched Felt

High Chemical Resistance & Reliable High-Temperature Performance

PPS Needle Punched Felt, also known as Polyphenylene Sulfide, is a premium choice among high-temperature filter media. Marketed under trade names like Ryton® or Procon®, PPS is widely acclaimed for its exceptional chemical resistance, especially in environments with strong acids, alkalis, and corrosive gases. It has become a standard filtration solution in some of the most demanding industrial dust collection systems.

💡 Key Advantages

  • Excellent Chemical Resistance: Performs exceptionally well in acidic, alkaline, and corrosive environments.
  • High-Temperature Tolerance: Continuous operation at up to 190°C (375°F).
  • Stable in Harsh Conditions: Maintains mechanical integrity and filtration efficiency even under thermal and chemical stress.
  • Low Moisture Absorption: Reduces the risk of hydrolysis and bag damage due to humidity.
  • Flame Retardant: Naturally flame resistant without added treatment.
