FIELD: laminated materials, in particular, duplex rubber materials, applicable for manufacture of hoses for supply of hydrocarbon fuel. SUBSTANCE: fluorine rubber СКФ-26, is used as a material for the inner layer, and mixed rubber СКР/ПВХ. - for the outer layer. The rubber mix for the outer layer in addition to СКР/ПВХ contains butadiene-nitrile rubber, triallizocyanurate, calcium carbonate and calcium hydroxide. EFFECT: enhanced strength of coupling between the chamber and the casing, only native raw material is used. 3 tbl |
