This glass-filled polyimide is exceptional in low-wear and low coefficient of friction conditions, in addition to a wide range of temperature tolerances––from 450º F up to 600º F continuously, and up to 750 F on occasion. Isomide PI 230 Data Sheet
Isomide Series - PI
ISOMIDE PI Series are completely imidized aromatic imide polymers 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.
PI-220 (20% Graphite-lubricated PI)
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 on occasion. PI-220 Data Sheet
PI-210 (15% Graphite and 5% PTFE-lubricated PI)
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. PI-210 Data Sheet
PI-200 (15% Graphite-lubricated PI)
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 pistons over a wide temperature range––from – 450o F up to 600o F continuously, taking 750o F for short periods.\\\\ PI-200 Data Sheet
PI-100 (PI)
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. PI-100 Data Sheet
