Description
The operating temperature of PPS is 160 ℃ - 190 ℃. PPS has excellent heat resistance, acid-base resistance and hydrolysis resistance. It is also a good flame retardant filter material with good thermal stability. However, PPS has poor oxidation resistance and is prone to oxidative corrosion.
Maximum Continuous in Dry Conditions: 190°C / 374°F
Maximum Surge in Dry Conditions: 200°C / 392°F
Typical applications
PPS is widely used in coal-fired boiler, also used in waste incinerator, coke oven, kiln, chemical drying process of flue gas purification. It is also used in carbon black, powder collection, pneumatic conveying and cement industry.
