Semitron® ESd 520HR has an industry first combination of electrostatic dissipation (ESd), high strength and heat resistance. This new ESd material is ideal for making nests, sockets and contactors for test equipment and other device handling components. The key features of 520HR are its unique ability to resist dielectric breakdown at high voltages (>100V). The graph below demonstrates the electrical performance of plastic materials commonly used in automated test handlers. Typical carbon fiber enhanced products become irreversibly more conductive when exposed to even moderate voltage.

Only Semitron® ESd 520HR maintains its performance throughout the voltage range, while offering the mechanical performance needed to excel in demanding applications.
