The PP needle punched felt, which used in liquidsolid filtration, selects different specifications of PP fibers and ordinary staple scrim or high strength filament scrim. That grams different from 350g/m2~700g/m2 and thickness different from 1.2mm~4.5mm all can be produced in our company, and can be divided into different widths. The post finished treatment includes singeing, calendaring etc.
