Semitron™ ESd 420V PEI electrostatic dissipative shapes possess high strength and stiffness and are not subject to dimensional change when exposed to moisture. This grade in particular offers a dissipative performance in the 10E5 to 10E8 ohms per square range and a heat deflection temperature of 215°C (419°F). Due to these characteristics, Semitron™ ESd 420V PEI is an excellent solution for device handling and test applications within the semiconductor and electronics industries.
