P84(PI-polyimide) is a filter material with the properties of flame resistance, high temperature resistance. Polyimide will keep a good performance when the temperature up to 240 degree centigrade, instant can up to 260 degree to 300 degree. 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.
