Our offered Film-Covered Needle Felt Bag filter is a composite filter material made of expanded PTFE (Polytetrafluoroethylene) (e-PTFE) micro-porous filter membrane on the surface of the original needle-punched felt filter material such as polyester felt, PET, PP, spinning cloth, etc. In addition to the characteristics, it is also resistant to various chemical corrosion, hydrolysis, hydrophobicity and condensation, ultraviolet and high temperature resistance, good dust removal efficiency and other characteristics. It also provides high filtering accuracy.
The coated filter material not only maintains the inherent high chemical stability, low coefficient friction, high and low-temperature resistance, and aging resistance of PTFE, but also resists the micro-particles, and the unmatched permeability of the conventional coated filter material. It is a new type of breathable coated membrane filter.
