| About |
|---|
| This PEEK based static dissipative material provides a dissipative range of 10E+6 – 10E+9 ohms/sq. Semitron® ESd 480 is very dimensionally stable, making it ideal for critical test fixture applications. Its exceptional chemical resistance makes it well suited for use in wafer handling and other structural applications in wet process tools where static dissipation is important. Like all Quadrant Semitron® ESd materials, Semitron ESd480 is not subject to dielectric breakdown.&& |
