Abstract

The results are presented of a study carried out to examine the environmental effects of moisture ingress, NaOH attack, and absorption of naphtha on the tracking or erosion performance of organic insulating materials. The materials studied were rod specimens of high-temperature-vulcanized silicone rubber, ethylene-propylene rubber, and epoxy resin containing various amounts of either alumina trihydrate (ATH) or silica powders. Exposure to boiling water, 0. 2N NaOH solution, or naphtha did not affect the tracking or erosion performance of the materials. Exposure to 6N NaOH solution greatly affected the performance of all materials containing ATH, but it is noted that such concentrations are unlikely to be encountered during service.
