Abstract

Electrical insulating compositions comprise a microcrystalline wax, e.g. slack wax or petrolatum grease, an insulating oil and 1 to 5% by weight of the composition of a "low pressure" polyethylene or polypropylene. The compositions may also comprise "high pressure" polyethylenes, high melting point Fischer-Tropsch waxes and polybutenes. Compositions described comprise white petrolatum and mixtures of mineral insulating oils with microcrystalline waxes of melting point 72 to 82 DEG C. Specification 777,706 is referred to.
