PPS Filter Bags
PPS Filter Bags
PPS (Polyphenylene Sulfide) filter bags are the optimal choice for harsh industrial conditions involving high temperatures and sulfur-rich gases. Known for their excellent chemical resistance, thermal stability, and long service life, PPS filter bags are widely used in waste incineration, coal-fired boilers, and chemical plants.
As a professional PPS filter bag manufacturer with 20+ years of deep R&D expertise, we produce high-quality 190°C continuous polyphenylene sulfide (Ryton®) needle felt using 100% Toray/Solvay virgin fiber. Our ISO 9001-certified process ensures superior acid & hydrolysis resistance, ideal for coal-fired boilers, waste incinerators, and chemical plants with SO₂/HCl.
Key Flue Gas Features:
- Outstanding corrosion resistance to SO₂, SO₃, HCl, HF
- Excellent hydrolysis resistance (stable in moist acid gas)
- Superior oxidation resistance up to 12% O₂
- Low pressure drop & easy cake release (minimal blinding)
- <10 mg/Nm³ emission in coal boiler & incineration
