This specification covers a polyimide plastic in the form of isostatically molded rod, bar, and tube, unidirectionally molded plaque, and direct formed parts. These products have been used typically for bushings, bearings, seals, and thermal-electrical insulators requiring a combination of toughness, low coefficient of friction, low wear, low creep, and good solvent resistance, but usage is not limited to such applications. Each application should be considered separately. Polyimide covered by this specification has a service temperature range of cryogenic to 500 °F (260 °C). These materials have no observable glass transition temperature (Tg) or melt temperature (Tm).
