PPS-Ryton Needle Felt,PPS-Ryton Needle Punched Felt,PPS-Ryton Needled Felt

PPS-Ryton Needle Felt

PPS Short fibers 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.

Features
1. Exceptional Stability for a Wide Range of Temperature and Frequency Variations
(working temperature 190℃, instantaneous operating temperature 230℃)
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 285℃, limited oxygen index 34~35;

Applications
• Coal - Fired Boilers bag houses
• Municipal Solid Waste Boilers and Waste incinerator
• Calciners / Catalysts
• Electric power plant
• Electrolysis and other Specialty membranes
• Waste to energy
• Iron and non ferrous Metal Industry
