Polypropylene filter medium

non-wovenairroll

The Polypropylene needle felt is kinds of common bag filters accessories. The raw material that we use to produce Felt filtration media is 100% polypropylene fiber. Through the needle punching process, we can freely change the fiber density and weight per square meter of the needled felt to make filter cloths with different filtration accuracy. The finish treatment of PP felt is different from PE material, it’s one-side glazed to prevent the fibers being scoured away by high-speed flowing liquid, thereby avoid the pollution of the filtrate by dropped fiber. Compared with PE needle felt filter media, the acid resistance of polypropylene needle felt Media is slightly worse, but the alkali resistance is much stronger. Therefore, PP non-woven filter fabric is also widely used in water treatment and other chemical industries. Features: Good alkali resistance. Fair acid resistance. Good air permeability. Working temperature: 90~110℃ Good Wear resistance. Restricted resistance to oxidation. Excellent resistance to hydrolysis.
