Reinforced rubber hose
摘要:
A reinforced rubber hose having a layer of ethylene-propylene rubber outside or inside a fiber-reinforcing layer. The two layers are firmly bonded to each other by an extruded adhesive layer of butyl rubber which exhibits a high bond strength after vulcanization. This obviates the necessity of treating (usually by dipping) the fibrous reinforcement with an adhesive before its braiding or knitting.
