Acrylic needle felt is a synthetic filter media made from acrylic staple fibers with excellent chemical resistance, particularly to acidic and alkaline gases. Designed for dust collection in medium-temperature environments (up to 140–150°C), it performs well in industries such as chemical processing, fertilizer production, and waste treatment plants. It is commonly used in baghouse systems where chemical corrosion is a concern. With moderate price and good dimensional stability, acrylic felt provides a balanced solution between performance and cost for industrial filtration projects under corrosive conditions.
Acrylic needle felt
Normally in filtration acrylic refers to homopolymer acrylic which is essentially made from 100% of acrylonitrile. Homopolymer acrylic needle felt and filter bags for industrial filtration. This kind of needle felt is with good ability of acid and alkali resistance, anti-oxidation, hydrolysis resistance. It suits middle temperature and high acid, alkali chroma environment. It is widely used in metallurgy, chemical, building material, electric power station, mechanism industry, petroleum, medicine, printing and dyeing, food and beverage, and other industries to filter gas and recycle material.
