Description
A polymer formed from the condensation product of an aromatic dianhydride and an aromatic diisocyanate. Polyimides are similar to polyamides but much more heat resistant. They can be formulated as either thermoplastic or thermosetting resins and have been used for adhesives, binders, and fibers. Polyimide fibers (P-84®) were developed in Austria. They have good chemical resistance and are flame retardant. Polyimide fibers are used in nonwoven fabrics, emission filters, and some types of protective clothing, especially in Europe.
