Isomide PI


ISOMIDE PI Series are completely imidized aromatic imidepolymers molded from polyimide powder resin utilizing Symmtek’s unique compression molding and sintering technology.

The wholly aromatic chain structure imparts high strength, thermal stability, rigidity, and hardness to ISOMIDE PI molded parts.

Polyimide black bushing


ISOMIDE PI-100: Unfilled base resin providing maximum mechanical properties, impact resistance, and elasticity combined with electrical and thermal insulating characteristics. This compound covers a wide temperature range from -450º F to 580º F continuous with excursions to 750º F for short periods.

ISOMIDE PI-200: 15% graphite lubricated composite with improved resistance to wear and low coefficient of friction. The choice grade for un-lubricated bearings, mechanical seals, thrust washers, and piston rings over a wide temperature range––from – 450º F up to 600º F continuously, taking 750º F for short periods.

ISOMIDE PI-210: 15% graphite, 5% PTFE lubricated grade offering the lowest coefficient of friction of bearing and wear surface operation under extreme pressure and velocity over a wide range of temperatures––from cryogenic to 600º F continuously, going up to 750º F for short periods.

ISOMIDE PI-220: 20% graphite lubricated compound offers low wear and low coefficient of friction under PV factors up to 130,000 in totally un-lubricated conditions. This has the same wide range of temperature tolerances as the other grades––from -450º F up to 600º F continuously, and up to 750º F intermittently.
