Semitron® CNT Polyoxymethylene POM-C is an extruded carbon nano tube-filled grade, developed specifically for electronic fixture applications that require a precise surface resistivity range, yet offer increased dimensional stability versus conventional POM ESd products. In addition to these properties, Semitron® CNT POM-C also offers superior stiffness and strength, while also maintaining an extremely low moisture absorption rate of 0.25% at 24 hour, and 0.75% at saturation. This grade in particular can be found throughout the semiconductor and electronics industry as integrated chip test jigs, test sockets, PCB test jigs, and in basic electronics assembly fixturing applications.
