PEEK/PI/PPS high-temperature resistant plastic bearings

PEEK, PI, and PPS, as emerging engineering plastic materials, have extremely high mechanical strength and dimensional stability, strong corrosion resistance, and the best high temperature resistance among all known engineering plastics. They can operate in almost all corrosive environments such as acid and alkali. Among them, PEEK and PPS have a long-term usage temperature of 260 ℃, and PI has a long-term usage temperature of up to 300 ℃
