Product Description

General introduction of the Polyimide (P*4, PI)needle felt filter cloth:

P*4(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 P*4 filter cloth is a perfect material and it always can meet very good filter efficiency.

Main applications of the P*4(PI-polyimide) filter bags:

Mainly used for Cement kiln, Asphalt, Waster Incinerator, coal boilers, etc.

The properties of the polyimide dust filter bags:

1. High temperature resistance: 

Recommended continuous operation temperature: ≤**0 degree C (for getting a longest service life, the continuous operation temperature suggest not exceed **0 degree C); instant peaks: **0 degree C.

2. Stable size under high temperature after heat setting treatment: at the **0 degree C , the shrinkage not exceed 1%. 

3. Fire proof.

4. Good abrasion and folding resistance.

5. High filter efficiency and long service life.
