Semitron® ESd 420 - ESd PEI (ULTEM)
OVERVIEW of Semitron® ESd 420 - ESd PEI (ULTEM)
Semitron® 420 is stocked in our USA, Singapore and Taiwan Warehouses. Semitron ESd 420 Static Dissipative PEI is the only, truly dissipative plastic product for use in high temperature applications. This material offers a unique combination of properties including: static dissipation, low coefficient of expansion, high strength and heat resistance and is non-sloughing. ESd 420 has a tensile modulus of 550,000 psi, a heat deflection temperature (at 264 psi) of 420°F, and a surface resistivity in the intermediate range of 106 to 109 ohms/square (W/sq.).
Semitron stock shapes for machining, is ideal for making fixtures for handling silicon wafers and devices in equipment for manufacturing semiconductor devices.

Semitron® ESd 420 is also ideal for use in equipment for handling components in the hard-drive manufacturing and assembly processes. Semitron® ESd 420 also has a low coefficient of thermal expansion, high compressive strength and good wear resistance. MCAM-Quadrant Semitron® ESd 420 shapes have very low residual stresses and as a result can be machined very flat and to very tight tolerances. Perhaps most importantly Semitron® ESd 420 is non-sloughing. As a result, it does not particulate significantly in these handling applications. Wafer combs and other parts for handling sensitive electronic components must be dissipative. More importantly they must be capable of discharging static electricity in a controlled manner. An uncontrolled discharge event can lead to damaged product. Semitron® ESd 420, which has a surface resistivity of 106 to 109 Ohms/sq., is ideal for use in such applications. Semitron 420 reliably meets all physical performance needs for wafer combs and other handling components, combined with stable ESd performance.
