Abstract

Insulating material for high voltage cables is obtained by mixing 40 to 60 parts by weight of ethylene propylene rubber with 60 to 40 parts by weight of a polyethylene of melt flow index 0.3 to 7.0, reacting the mixture in an internal mixer or on a mill at temperatures above 130 DEG C. in the presence of an organic peroxide and elemental sulphur, and then using the partially cross-linked polymer blend thus prepared as a filler for an ethylene propylene rubber composition. 1 part by weight of peroxide, e.g. dicumyl peroxide, and 0.2 parts by weight of sulphur may be used. Fillers may be added to the final mixture.
