PPS (Polyphenylene Sulfide) Fibers Features
1. Exceptional Stability for a Wide Range of Temperature and Frequency Variations
(working temperature 190ºC, instantaneous operating temperature 230ºC)
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 285ºC, 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 165ºC, pps will be in decomposition.
Applications
