    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: A hose for refrigerant fluid or fuel oil service which comprises a core tube, a reinforcing layer and an outer cover, the core tube being of a composite structure having an inner plastic peripheral wall, an intermediate plastic peripheral wall and an outer rubbery peripheral wall. The inner and intermediate walls are formed of a selected class of polyamides and polyolefins, whereby the hose is rendered highly impermeable to fluid and moisture, greatly resistant to stress cracking and sufficiently flexible.
