FLEXIBLE HOSES HAVING A KINK, CRUSH, AND BURST RESISTANT CONSTRUCTION

摘要

A flexible hose construction with enhanced levels of kink, crush, and burst resistance. The hose includes an inner tubular member, an outer tubular member, a yarn layer disposed between the inner and outer tubular members, and a plurality of reinforcement strips within the outer tubular member. The reinforcement strips are helically wound with a given pitch about the lumen of the tubular member. The outer tubular member is composed of a first compound containing an olefin block copolymer and a styrene/ethylene-butylene/styrene-based thermoplastic elastomer. The reinforcement strips are composed of a second compound containing a thermoplastic elastomer and a polypropylene homopolymer.
