Abstract
Very high levels of insulation resistance and of insulation resistance stability of insulating compositions having polyolefin bases and having polar organic additives are achieved in this invention. The polar organic additives can be organic halogenated flame retardants, such as decabromodiphenyl oxide. The surprising increase in insulation resistance and in insulation resistance stability is achieved by addition of certain antioxidants in combination and, particularly, the addition of a zinc salt of mercaptoimidazole and a sterically hindered di-tertiary butyl phenol. The composition may be crosslinked by radiation or even by chemical means as through use of organic peroxides without loss of the surprisingly increased insulation resistance and insulation resistance stability.
