PPS Filter Bag

Materials: 100% PPS  
Operating temperature: 160°C to 190°C.  
Working conditions: PPS filter bags are used in dust filtration systems / dry dust recovery systems, with moderate oxidation resistance, but excellent hydrolysis, acid, and alkali resistance.  

At VIFICO, customers will receive support for surveys, consultations, and free samples.  
All dust filter fabrics are imported 100% from reputable, quality suppliers, and have been carefully selected. VIFICO provides complete import documents CO, CQ.  
Dust filter bags are produced on a European standard technology line, achieving a capacity of more than 20,000 products per month with a team of workers who have many years of experience in the industry.

PPS FILTER BAG   

Characteristics  
The PPS (Polyphenylene Sulfide) dust filter bag is made from non-woven dust filtering fabric, capable of withstanding temperatures from 160°C to 190°C, has high abrasion resistance, moderate oxidation resistance, but excellent hydrolysis resistance, and good acid and alkali resistance compared to Nomex dust filter bags and Acrylic dust filter bags in hot and humid dust environments.  

PPS is widely used in the production of dust filter bags for boilers, waste-to-energy plants, waste incineration - waste treatment, thermal power, and coal gasification.  

Examples:  
- The PPS dust filter bag recovers/treats industrial dust at high temperatures in effective hydrolysis environments.  
- In high adhesive dust environments, the PPS dust filter bag is treated with moisture resistance.  
- For fine dust <2.5 microns, which is acidic or alkaline, requiring low emission concentrations, choose PPS filter fabric made from fibers with a small diameter and fabric weight from 550 - 600g/m², treated with a PTFE membrane...  

Applications  
In Vietnam, PPS dust filter bags are used across all industries that generate dust in some positions or throughout the entire production process, such as:  
- Building materials industry: Cement, Steel, Gypsum, Ceramics...  
- Mining and mineral processing: Stone powder, Sand, Glass, Aluminum, Non-ferrous metals...  
- Animal feed and food, Pharmaceuticals, Tobacco  
- Other industries: Wood, Fertilizers, Batteries, Tires, Plastics, Waste treatment, Boilers, Thermal power, Hot asphalt...
