Sultron™ Polysulfone PSU is a translucent material that offers a combination of excellent mechanical, thermal, and electrical properties. This grade often replaces polycarbonate whenever higher temperature resistance, improved chemical resistance, or autoclavability is required. Sultron™ PSU shapes are ideal for analytical instrumentation and semiconductor process equipment components due to their outstanding radiation stability, and resistance to acidic and salt solutions, detergents, hot water, and steam.
