Pp Filter Bag
Polypropylene filter bags is polypropylene needle felt material. Polypropylene felt filter bags has good wear resistance and high elastic recovery rate. When the load increases, the creep elongation of polypropylene fiber is greater than that of polyester fiber. Polypropylene filter bags can withstand 90 degree temperature. The chemical property of polypropylene pp filter bag is a good neutral product of all chemical fibers. It is acid proof and alkali resistant. It is resistant to other acids except for chlorinated sulfonic acid and concentrated nitric acid. National filter environmental protection is a professional polypropylene fiber needle felt manufacturer, the variety of products, the material used by the scientific verification, used for filtering can play an effective role, high filtering precision. In addition, polypropylene needle felt price is favorable and quality is excellent.
