ABSTRACT:
Vulcanizates of so-called EPM and EPDM rubber compositions can be imparted with greatly improved flame retardancy and emit a greatly decreased volume of smoke in burning when the rubber composition is compounded with a conventional flame retardant agent of aluminum or magnesium hydroxide together with a polymer of an acrylic acid ester and an organopolysiloxane in combination or a copolymer composed of the moieties of these two kinds of monomeric units in a limited weight proportion.
