摘要： Rubber compositions are disclosed for integral attachment of polymeric and metallic materials. Improved bondability is attributed to the use of a selected base rubber blended with a selected class of inorganic or organic fillers, silane compounds and vulcanizing agents such that the finished composition is provided with a specified range of Mooney viscosities. Also disclosed is a method of hose-metal fitting connection by the application of the composition. Gas- and oil-impermeability characteristics are greatly enhanced.

摘要： Hoses for transporting or otherwise handling refrigerant and oil fluids are disclosed which are comprised of an inner tube, an outer cover and a reinforcing layer interposed therebetween. The inner tube includes at least two walls, one being an inner resinous wall and the other being an outer rubbery wall having specified moduli at 100%. The outer cover is formed by a selected class of rubbers having a higher modulus at 100% than the outer wall of the inner tube. The resulting hose is securely interconnectable with metal fittings, highly impermeable to gaseous and oily fluids, sufficiently resistant to stress cracking and adequately flexible.
