Polyimide (P84) needle felt for dust collector systems

Polyimide (P84) needle felt for dust collector systems

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.
