EpiSpire® EP-340 is a high-temperature, high-performance, amorphous, sulfone polymer. With a glass transition temperature of 265°C (509°F) and a heat deflection temperature of 255°C (491°F), EpiSpire® EP-340 resin offers one the highest glass transition temperatures for fully thermoplastic transparent resin. In addition to this exceptional thermal performance, this resin exhibits the other performance features and attributes typical of aromatic sulfone polymers. These features include good strength, stiffness, and dielectric properties over a wide temperature range, resistance to hydrolysis by hot water and steam environments, excellent resistance to acids and bases, and inherent flammability resistance. The resin also offers a high degree of dimensional control during fabrication and dimensional stability during part service life.
