Specifications

1. High Temperature resistant
2. Good chemical resistance
3. Good air permeability, High filtration efficiency
4. Dimensional

P84 has excellent property of flame and high temperature resistance which use in long-term temperature of 240°C , peak can up to 260°C to 300 °C.  P84 is leaf-shaped structure with a larger filter surface, and always embedded in the surface of other needle felt with different material to improve the filter efficiency.

It is mostly applied in Cement kiln, Asphalt, Waster Incinerator, coal boilers, etc.
