Effect of the processing method on the treeing resistance of polymeric dielectrics

Abstract

Results of investigation into the effect of the processing method on the treeing resistance of polystyrene, polymethylmethacrilate, and polycarbonate are presented. It is demonstrated that in the presence of residual internal strain arising at the stage of processing, the highest treeing resistance possess polymers with a higher tensile yield strength. The tree propagation rate can be decreased and the time to breakdown of polymeric dielectrics can be increased by decreasing the thermal diffusivity of the base polymers.
