A multilayer automotive hose includes an innermost layer 11 of elastomer material, and a separate outermost layer 12 of elastomer material, each including between about 40% and about 80% vinylacetate by weight in a copolymer. The elastomer layers 11, 12 are formed by an extrusion process. The vinylacetate is copolymerized with polyethylene. Each of the elastomer layers 11, 12 has a fully saturated backbone. As a result, each of the innermost and outermost layers 11, 12 is a non-thermoplastic elastomer. <IMAGE> |
