ABSTRACT:
Track and erosion resistant electrical insulating materials are disclosed comprising (a) a base insulating material comprising a polymer of ethylene and additives necessary to allow the polymer to function as electrical insulation, and (b) hydrated zinc borate as an anti-tracking and anti-erosion additive. The hydrated zinc borate functions to increase the track and erosion resistance of the electrical insulating material in concentrations of as little as 1% by weight of the entire material with its maximum effect being achieved at concentrations of about 25% by weight of the entire material.
