PP filter element is made of superfine polypropylene fiber by hot melt entanglement. Superfine fibers rely on their own adhesion and entanglement to form a three-dimensional microporous structure randomly in space. There is no need for any adhesive to connect the fibers. In particular, the radial fibers have the characteristics of gradient change.
It is a complex of porous and fabric filter media. On the one hand, it can form deep filtration (the characteristics of porous filter material), on the other hand, it can form surface filtration (the characteristics of fabric filter material). It is a composite filter material integrating pre filtration, fine filtration and gravity sedimentation. It has been widely used in drinking water purification, industrial pure water filtration and other fluid filtration.
