    Overview of Polyimide Materials

    — Thermosetting Polyimides (PI) are available as stock shapes, thin sheets, laminates & machined parts. Polyimides are known for thermal stability, good chemical resistance & excellent mechanical properties. They exhibit very low creep & high tensile strength. These properties are maintained during continuous use to temperatures of 450°F (232°C) and for short excursions, as high as 900°F (482°C). Molded polyimide parts & laminates have very good heat resistance. Normal operating temperatures for such parts and laminates range from cryogenic to those exceeding 500°F (260°C). Polyimides are also inherently resistant to flame combustion and do not usually need to be mixed with flame retardants. Most carry a UL rating of V-0. Typical polyimide parts are not affected by commonly used solvents & oils — including hydrocarbons, esters, ethers, alcohols and freons. They also resist weak acids but are not recommended for use in environments that contain alkalis or inorganic acids.
