Polyimide (PI)

Polyimide is a non melting high temperature polymer. Strength, dimensional stability, and creep resistance remain high even at temperatures above 300°C. Low wear rates combined with the ability to work under unlubricated conditions and high pV-rates makes it the ideal material for challenging friction and wear applications, extending lifetime and reducing maintenance costs. Its high purity and low outgassing are needed for applications in the vacuum, space and semiconductor industry.

Grades

• PI-N (comparable to Vespel SP-1)
PI-N is the unfilled base resin grade. It provides maximum physical strength, elongation, and toughness as well as the best electrical and thermal insulation values. Typical applications include spacers, high-temp fixtures, valve seats, balls, gaskets, insulators, and seals.
• PI-G15 (comparable to Vespel SP-21)

PI-G15 has 15% graphite by weight added to the base resin for increased wear resistance and reduced friction in applications such as bearings, thrust washers, bushings, seal rings, slide blocks, and other wear applications. G15 has the highest mechanical properties of the graphite-filled grades.
