1. P84/ Polyimade needle felt is made of polyimide fiber byneedling craft. It has remarkable
high temperature endurance and acid, alkali resistance. It possesses advantages of anti-chemistry property. P84 fiber is efficient in collecting micro grain and little differential pressure.
It can be continuously used in asphalt factory, cement, waste incinerator, fluid boiler.
and coal-burning boiler etc.
