Hongyuan Envirotech manufactures a wide range of needle felt for dust filtration. Needle felt is a type of filter material created using various chemical fibers such as Polyester, PP, Acrylic, PPS, Aramid, fiberglass, PTFE, and P84. Our needle felt is produced using a unique needle punching process and high strength filament scrim. We typically treat the felt surface with heat setting, singed and glazed finishes. Additionally, we offer PTFE and water and oil repellent finishes based on customer requests and specific applications. Our advanced equipment and technology greatly enhance the cleaning capacity, stability, and filtering accuracy of the filter materials, resulting in an extended service life. Our needle felt finds wide application across industries including Metallurgy, Chemical industry, Cement, Power plant, Medicine, and Waste incineration plant, among others.
Acrylic needle felt filter cloths are commonly used in industrial filtration. These filter cloths are made from homopolymer acrylic, which is composed entirely of acrylonitrile. They possess strong resistance to acids, alkalis, oxidation, and hydrolysis, making them suitable for environments with high acid and alkali levels and moderate temperatures. Acrylic needle felt filter cloths are extensively utilized in various industries, including metallurgy, chemicals, construction, power generation, machinery, petroleum, medicine, printing, dyeing, food, and beverages, for gas filtration and material recycling.
Key Features:
• Exceptional mechanical properties
• Outstanding resistance to hydrolysis
• Excellent heat stability in both dry and wet conditions
• Optimum resistance to chemical substances
• Remarkable durability against light, weathering, mildew, and bacteria.
