| Reinforced with a proprietary synthetic mica, Semitron ESd 500HR offers an excellent combination of low frictional properties, good dimensional stability and electrostatic dissipation. Whenever virgin PTFE causes electrical discharge problems, Semitron ESd 500HR will provide a controlled bleed-off of static charges while maintaining typical PTFE-properties such as broad chemical resistance and low coefficient of friction Surface resistivity: 1010 – 1012 ohms/sq Thermal performance to 500°F (260°C) Thermally insulative Very low coefficient of friction Broad chemical resistance&& |
