Material Data Sheet
Material: Semitron® ESd 480
Static Dissipative Polyetheretherketone (PEEK®)This PEEK® based static dissipative material provides a dissipative range of 106 - 109 ohms/sq. Semitron® ESd 480 is dimensionally stable, making it ideal for test fixtures. PEEK®'s chemical resistance makes it a good material for wafer handling devices and is a good option in wet environments where static dissipations is critical. Semitron® ESd480 is not subject to dielectric breakdown.
