Acrylic rubber composition for heat-resistant hose and heat-resistant hose using the same

Abstract

Provided are an acrylic rubber composition for a heat-resistant hose having high electric resistance and high strength and being excellent in suppression of the generation of bubble marks at the time of the production of a hose and a heat-resistant hose using the acrylic rubber composition for a heat-resistant hose. An innermost layer of the heat-resistant hose is formed by using an acrylic rubber composition for a heat-resistant hose, containing the following components (A) to (C) and having a content ratio between the component (A) and the component (B), (A)/(B), of from 95/5 to 45/55 in terms of a weight ratio: (A) an ethylene-acrylic rubber (AEM); (B) an acrylic rubber (ACM) excluding the component (A); and (C) carbon black having a value of iodine adsorption amount (mg/g)×DBP absorption amount (cm3/100 g) of from 1,500 to 7,200.
