PPS needle punched filter felt

The raw material is made of polyphenylene sulfide(PPS) fiber produced in the a pan and China.The fiber has excellent chemical resistance.It can withstand almost all acids,all kalis andl organic solvents,except for strong oxidants,which can be below 190℃Long-term use at temperature,especially resistant to Sog and Soy corrosion.It has good hydrolysis resistance.Even if it is exposed to high temperature(160℃) and high humidity(79%) for along time(500h) ,its strength wil not be lost.It is very suitable for occasions where the flue gas contains warm air.PPS fiber has complete retention of strength and inherent chemical resistance,which can maintain good filtration performance in harsh environments and achieve an ideal service life.
