PPS fiber can keep intensity completely and bear chemistry nurturing inherently, keep good filtration performance among the abominable environment, reach ideal service life.

Features: 190 ºC of working temperature, 220ºC of short-term working temperature, 285 ºC of melting point. It is also available when the oxyen content is below 14%, but the operation temperature should be lowered. When there is humid and of high adhesivity, high concentration, it could be chosen.

 

In coal boiler, rubbish incinerator, power plant of fly ash filtering of pulse clear dust catcher PPS filter felts are an ideal filtration material.
