PPS Filter Bag

Filter bag introduction：

1. Excellent High-Temperature Resistance

• Continuous operating temperature: Up to 160°C (320°F)

• Short-term surge temperature: Up to 190°C (375°F)

• Stable performance under long-term high heat, with minimal thermal shrinkage

2. Outstanding Chemical Resistance

• Resistant to most acids, alkalis, organic solvents, and oxidizing gases

• Strong hydrolysis resistance, suitable for high-humidity and dew-point crossing conditions

• Performs reliably in sulfur-containing flue gas (e.g., coal-fired boilers)

3. Inherent Flame Retardancy

• Limiting oxygen index (LOI): 34–35%

• Self-extinguishing when removed from an open flame; low smoke and low flame spread

4. High Mechanical Strength & Durability

• High tensile and tear strength; excellent abrasion resistance

• Stable shape retention under pulse-jet cleaning and airflow impact

• Low thermal shrinkage, maintaining dimensional stability at high temperatures

5. Superior Filtration Performance

• Fine fiber structure with controlled porosity, efficiently capturing fine and ultrafine particulates

• Good dust release property, easy to clean, and maintains low pressure drop

• Meets strict industrial emission standards

6. Long Service Life & Easy Maintenance

• Resists heat, corrosion, and mechanical fatigue, extending service life vs. conventional filter media

• Easy to install and maintain, reducing system downtime

  
  

  
  

• Common Applications

• Coal-fired power plants (for sulfur-heavy emissions).

• Waste-to-energy plants (incinerators).

• Carbon black production.

• Smelting and metal refining.
