Abstract

A rubber insulating pad for positioning between an electrically-conducting rail and its support is moulded from a composition comprising polychloroprene, polyisobutylene and powdered asbestos. Antioxidants, such as a condensation product between a ketone and an aromatic amine, and fillers such as lampblack and kaolin, may also be present.
