High temperature dedusting felt

PPS needle felt

PPS needle felt is a new type filter cloth of withstanding high temperature and acid, alkali resistance by needling craft,

made of PPS fiber produced by American Dupont company and Japanese Teijin company.

 

PPS needle felt possesses the advantages of acid and alkali resistance, anti-hydrolysis, fit stability, flame retardation, long working life etc.

It can be utilized in conditions of humidity, chemical corrosion and high temperature.

 

PPS needle felt widely used in power plant coal burning boiler,incineration,,coal ash collection treatment,metal smelting etc.
