ULTEM® polyetherimide resin is characterized by a combination of high performance mechanical, thermal, flammability, and electrical properties. The exceptional mechanical properties are typified by a 15,000 psi tensile strength and 480,000 psi flexural modulus. Because of its amorphous structure and outstanding adhesion to glass, ULTEM® proves to be a very desirable matrix material for glass fiber reinforcement. Addition of fiber glass enhances most mechanical properties and provides a readily processible reinforced thermoplastic.
