STATIC-DISSIPATIVE PLASTIC

A new electrostatic dissipative (ESd) plastic from DSM Engineering Plastic Products has a unique combination of properties: static dissipation, low coefficient of expansion, high strength, high heat resistance and non-sloughing. Semitron® ESd 520HR has a surface resistivity of 1010 to 1012 ohms/square, a tensile modulus of 800,000 psi and a heat deflection temperature (at 264 psi) of 520ºF.

The new material, which is available in stock shapes for machining, is ideal for making static-dissipative nests, sockets and contactors for testing semi-conductor devices, and other device-handling components.

The material also has a low coefficient of thermal expansion, high compressive strength, good wear resistance and can be machined to very tight tolerances, all of which are important benefits for nests and sockets used in testing semiconductor devices.
