Abstract
An acrylic rubber composition in which the base material is an acrylic rubber comprising monomer units of ethyl acrylate, n-butyl acrylate, and cure site monomer, with a ratio (B/A) of the amount of n-butyl acrylate (B) with respect to ethyl acrylate (A) of 1.0 or less by weight. A heat-resistant hose having a layer of this acrylic rubber composition as the innermost layer. The above constitution of the invention provides the acrylic rubber composition effective for preventing aluminum fixing while retaining the material properties of acrylic rubber and its excellent characteristics. The present invention also provides a heat-resistant hose using this acrylic rubber composition at the surface which is to be fitted with an aluminum member.
