Rubber compositions containing ethylene-propylene-diene terpolymers or ethylene-propylene copolymers and silicones
Abstract
A rubber made from a blend of EPDM or EPR and a polydiorganosiloxane gum has strength, heat resistance, and adhesiveness to a room-temperature, moisture-curable silicone rubber. The rubber is made from a blend of EPDM or EPR, polydiorganosiloxane gum, a polyorganosiloxane containing aliphatic hydrocarbon radicals of 4 to 20 carbon atoms, a polyoxyalkylene-organosiloxane copolymer or a poly(hydroxyalkyl)organosiloxane, and an organic peroxide.
