Rubber composition and hose

Abstract

An object of the present invention is to provide a rubber composition that is excellent in extrudability, adhesiveness to a reinforcing material, and weather resistance. The present invention is a rubber composition including a rubber component containing 80 mass % or more of an ethylene-propylene-ethylidene norbornene copolymer satisfying Formula (I), magnesium oxide, carbon black, and a vulcanizing agent, and a hose formed by using the rubber composition. 3.5≥EE/(EP×ENB×Mn)×106≥0.7 (I). In Formula (I), EE is the content (mol %) of an ethylene-ethylene chain structure, EP is the content (mol %) of an ethylene-propylene chain structure, ENB is the content (mass %) of ethylidene norbornene, and Mn is the number average molecular weight of the ethylene-propylene-ethylidene norbornene copolymer.
