PPS High Temperature Resistant Needle Punched Filter Felt Dust Collect Bag

PPS High Temperature Resistant Needle Punched Filter Felt

PPS Short fibers can keep intensity completely and bear chemistry maturing inherently, keep good filtration performance among the abominable environment, reach ideal service life. In coal boiler, rubbish incinerator, power plant of fly ash filtering of pulse clear dust catcher, PPS filter felts are an ideal filtration material.

PPS(Polyphenylene Sulfide) Fibers Features

1.     Exceptional stability for a wide range of temperature and frequency variations (working temperature 190centidegree, instantaneous operating temperature 230centidegree)

2.     be suitable for the oxygen content below 15%

3.Chemical resistance to acids, alkalis and organic solvents

4. Containing moisture in the flue gas, hydrolysis resistance

5.Very stable in finished felt form with stability standards at 2% shrink or stretch.

6. Favorable temperature resistance melting point 285cetidegree, limited oxygen index 34-35
