Technical description of P84 (polyimide) / PTFE (polytetrafluoroethylene) composite needle felt filter bag

According to the requirements of the technical specifications and working conditions, our company uses the excellent PTFE (polytetrafluoroethylene) staple fiber + P84 (polyimide) fiber + PTFE (polytetrafluoroethylene) base cloth produced by Japan Toray company as the raw material and uses our mature needling process and German host equipment. In order to ensure the filtration accuracy required by working conditions, our company is selecting PTFE (polytetrafluoroethylene) fiber and P84 (polyimide) fiber for blending, Combined with the effective post-treatment of impregnation and membrane infiltration process, most of the fiber surfaces are protected by nano coating, which not only improves the performance of the needle felt, but also achieves a qualitative breakthrough in the filtration accuracy, which is easy to meet the emission requirements of working conditions. Low pressure difference, high filtration accuracy and corrosion resistance are the remarkable characteristics of the product.
