Abstract

533,520. Electrical insulating compositions. PIRELLI-GENERAL CABLE WORKS, Ltd., and BARRON, H. Aug. 17, 1939, No. 23711. [Class 2 (iii)] An electrical insulating composition consists of polyisobutylene in admixture with a high melting point bitumen to which hard coumarone or indene resin, wax and a filler such as talc may be added. The Provisional Specification describes also compositions containing polyisobutylene and coumarone resin.
