PPS (polyphenylene sulfide or Rayton) needle felt is a high-performance filter material, mainly used in applications that require resistance to high temperatures and corrosive chemicals. PPS is a special synthetic polymer that can maintain stability under high temperature and chemical corrosion conditions, so it is often used in industrial flue gas purification and high-temperature gas filtration.
- High Temperature Resistance.
- Chemical Stability.
- Low Hygroscopicity.
- Abrasion Resistance.
- Good Mechanical Strength.

Description
Main Features of PPS Needle Felt Filter Cloth
- High Temperature Resistance: PPS has excellent high temperature resistance and is able to work in high temperature environments, usually up to temperatures above 190°C (374°F).
- Chemical Stability: PPS material shows strong stability to a variety of chemical corrosive substances, so it is suitable for some filtering environments with corrosive gases or chemical substances.
- Low Hygroscopicity: PPS material has very low hygroscopicity and can maintain stable performance in humid environments.
- Abrasion Resistance: PPS needle-punched filter felt is relatively wear-resistant and suitable for industrial filtration environments that require long-term use.
- Good Mechanical Strength: PPS material has good mechanical strength to a certain extent, and can withstand certain tension and pressure during the filtration process.
