Polyphenylene Sulfide (PPS) fiber filter bags are high-performance industrial filtration products made from polyphenylene sulfide fiber, offering exceptional heat resistance, chemical corrosion resistance, and durability. PPS fiber is ideal for high-temperature, highly corrosive environments, such as dust collection and gas purification in demanding industrial applications.
Key Features
- High-Temperature Resistance: Continuous operating temperature ≤190°C (short-term exposure up to 220°C, subject to working conditions).
- Chemical Resistance: Resistant to acids (e.g., SO₂, HCl), alkalis (e.g., NH₃), and organic solvents (e.g., xylene), making it suitable for coal-fired boilers, waste incineration, and other corrosive environments.
- Oxidation Resistance: Performs exceptionally well in high-temperature flue gas with ≤15% oxygen content. Prolonged exposure to high oxygen (>15%) may cause degradation.
- High Filtration Precision: Standard filtration efficiency of 1–10μm; with membrane coating, it can capture ultrafine particles down to 0.5μm.
Low Moisture Absorption: Minimal impact on filtration performance under varying humidity. - High Mechanical Strength: Excellent abrasion and tensile resistance, suitable for high filtration velocity (≤1.5 m/min).
Applications
Power Industry: Flue gas filtration in coal-fired power plants and biomass boilers (paired with baghouse dust collectors).
Chemical Industry: Acidic gas filtration in sulfuric acid and fertilizer production.
Waste Incineration: Flue gas treatment in incinerators (resistant to dioxin corrosion).
Metallurgical Industry: High-temperature dust collection in aluminum electrolysis and steel sintering.

Usage Guidelines
Operating Conditions:
Flue gas oxygen content ≤15%, operate above dew point temperature.
Avoid prolonged exposure to strong oxidizers (e.g., concentrated nitric acid, ozone).
Installation Requirements:
Check tube sheet flatness before installation to prevent bag abrasion.
Pre-coating (e.g., lime powder) is recommended for initial operation.
Maintenance & Cleaning
Offline pulse-jet cleaning pressure: 0.4–0.6 MPa.
Do not use strong acid/alkaline cleaning agents.
Storage & Transportation
Store in a cool, dry place away from fire and corrosive substances.
Avoid hooks or heavy pressure during transport to prevent mechanical damage.
Quality Assurance
12-month warranty (under normal operating conditions).
Third-party test reports available (e.g., ISO 11057 filtration efficiency test).
