P84 Polyimide PI High Temperature Filter Bag

Introduction of PI filter bag

P84(Polyimide) high temperature resistant needle felt is made from Polyimide fiber and it is a new high efficient filter material with high temperature resistance.acid and alkali resistance produced by non woven needle techniques.

Feature of PI filter bag

P84 (Polyimide)needle felt has excellent property of temperature resistance,which use in long-term temperature of 260℃ in the environment.

P84 features due to the fineness of the fiber itself significantly and more due to the irregular surface area of fiber cross section which increased the fiber  to provide the largest number of tiny pores to filter better than the depth of the surface filter. dust filter needle felt only stay in the surface but failed to penetrate the filter felt. and therefore the pressure against the small and the filter cake washed off bombs to significantly improve the efficiency with excellent micro-powder collection efficiency and the operating pressure difference.

Application of PI filter bag

It is widely used in cement plant . steel plant. power plant. water incineration. asphalt works. coal burning boiler etc for air filtration.
