Semitron® ESD 500HR PTFE Polytetrafluoroethylene

Semitron® ESD 500HR PTFE electrostatic dissipative shapes offer an excellent combination of low frictional properties, outstanding dimensional stability, and a high resistivity range of 10^10 to 10^12 ohms per square (antistatic range). Reinforced with a proprietary synthetic mica, Semitron® ESD 500HR PTFE is thermally stable up to temperatures of 500° F/260° C without degradation, possesses high thermal insulation, and a low coefficient of friction. Due to these characteristics, this grade is ideal for applications where controlled bleed-off of static charges is critical.
