Description
PPS (Ryton) Non Woven Needle Felt Filter Cloth
PPS (Polyphenylene Sulfide) Fibers Features
• Exceptional Stability for a Wide Range of Temperature and Frequency Variations
• Be suitable for the oxygen content below 15%;
• 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 285℃, limited oxygen index 34~35;
Disadvantages
Fair resistance to oxidation under high temperature
When the oxygen in the smoke ( O2 content) over 10% and the operating temperature over 165℃, PPS will be in decomposition.
