PURPOSE:To obtain a rubber hose which is excellent in heat resistance in the inner and outer layers and has strong strength by utilizing a specified compd. such as EPM, EPDM and silicone rubber and constituting the rubber hose of a double structure. CONSTITUTION:A rubber hose is obtained which has a two-layer structure constituted of an outside and an inside described hereunder. This out-side is formed of the mixture of both an ehtylene-propylene-based organic polymer of an ethylene-propylene-diene-based organic polymer and organopolysiloxane. The inside is formed of silicone rubber, the ethylene-propylene-based organic polymer of the ethylene-propylene-diene-based organic polymer. The inner and outer layers of the rubber hose are excellent in hear resistance and the outside is strong in strength. Therefore this rubber hose is especially available as a radiator hose of an automobile and an air hose. |
