Thermoplastische elastomere Schläuche mit hervorragender Flexibilität

摘要

A hose including at least an inner tube, a reinforcing layer and an outer cover, wherein the inner tube and the outer cover are individually composed of a thermoplastic elastomer comprising a vulcanized rubber dispersed in a thermoplastic resin, Mp defined by the following formula (I) is not greater than 70 kgf/cm2, and flexural rigidity of the hose at a bending radius four times the outer diameter of the hose is 1 kgf or less: (I) wherein t1 and t2 are the thickness of the inner tube and the outer tube (mm), respectively, and M1 and M2 are stress (kgf/cm2) at 25% elongation of the inner tube and the outer cover, respectively.
