Polyimide (PI) Resins

Polyimides appear as amber to dark-colored materials with exceptional thermal resistance. Key features include exceptional heat resistance (often exceeding 400°F continuous use), excellent dimensional stability, and superior electrical properties. Polyimides excel in electronics assembly, aerospace components, and high-temperature industrial applications. 

Market trends include the development of more processable grades with improved handling characteristics, enhanced toughness, and impact resistance. Sub-types include thermoplastic polyimides, thermoset grades, polyimide-silicone hybrids, and polyimides as films.
