PURPOSE:To obtain a material for forming a hose, having high flexibility and excellent oil resistance, heat-resistance and Freon gas permeation resistance, by combining a polyamide and/or polyamide elastomer with a rubber at a specific compositional ratio. CONSTITUTION:The objective material can be produced by compounding (A) 95-25wt.% (preferably 70-40wt.%) of a polyamide (e.g., nylon 11, nylon 12, etc.), and/or a polyamide elastomer with (B) 5-75wt.% (preferably 30-60wt.%) of a rubber. The component B is preferably a rubber modified with a modifying agent during or after the preparation and having a functional group selected from carboxyl group, hydroxyl group and epoxy group. |
