PPS high temperature resistant needle-punched filter felt：
PPS fiber can keep intensity completely and bear chemistry naturing 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 filter felt is one of the main filter material able to bear the high temperature according to processed of production technology and artificial material of other high-temperature filter felt. 
 
PPS (Polyphenylene Sulfide) Fibers Features
• Exceptional Stability for a Wide Range of Temperature and Frequency Variations
• Be suitable for the oxygen content below *5%;
• Chemical Resistance to Acids, Alkalis and Organic Solvents
• Containing moisture in the flue gas; Hydrolysis Resistance
• Very stable in finished felt form with stability standards at 2% shrink or stretch.
• Favorable temperature resistance melting point **5℃, limited oxygen index *4~*5;
Advantages：
PPS Ryton nonwoven needle felt dust filter bag
1.ISO***1:***8
2.USA standard
3.high quality and long useful life
 
Disadvantages
Fair resistance to oxidation under high temperature
When the oxygen in the smoke ( O2 content) over *0% and the operating temperature over **5℃, PPS will be in decomposition
