Polyimide is leaf-shaped structure with a larger filter surface, and always embeded in the surface of other needle felt with different material to improve the filter efficiency. For the properties of high Temperature resistant Filter material, good chemical resistance, good air permeability, high filtration efficiency, mostly applied in Cement kiln, Asphalt, Waster Incinerator, coal boilers, etc.
