General introduction of the Polyimide (P84, PI)needle felt filter cloth: P84(PI-polyimide) fiber with the properties of high temperature resistance and inflammable, the tri-leaf structure of the fiber help the polyimide needle felt filter cloth with a much lager filter surface when compare to the filter cloth with the other fibers, so the P84 filter cloth is a perfect material and it always can meet very good filter efficiency.
Relevant specification for the P84 needle felt: Material: P84(PI-polyimide) fiber, supported with P84(PI-polyimide) / PTFE scrim Weight:450~650g/sq.m Operation Temperature: Continues: ≤240ºC; Peaks: 260ºC Surface treatment available: singed & glazed, heat set, PTFE suspension bath, PTFE membrane. We can customize the products according to the requirements from the clients!
The properties of the polyimide dust filter bags: 1. High temperature resistance: Recommended continuous operation temperature: ≤240 degree C ; instant peaks: 260 degree C. 2. Stable size under high temperature after heat setting treatment: at the 260 degree C , the shrinkage not exceed 1%. 3. Fire proof. 4. Good abrasion and folding resistance. 5. High filter efficiency and long service life.
Main applications of the P84(PI-polyimide) filter bags: Mainly used for Cement kiln, Asphalt, Waster Incinerator, coal boilers, etc.
Note: 1. Special specification can be customized. 2. maximum width:2.25meters. 3. both filter cloth rolls and filter bags are available to supply from Zonel Filtech.
