Patent number: 12031658Abstract: A multi-layered hot melt adhesive transfer hose is provided. The transfer hose has a barrier layer that prevents or minimizes the ingress of oxygen and other gases into a conduit of the hose. The transfer hose has at least one structural layer overlaying an exterior surface of the barrier layer to help the hose withstand a high fluid pressure. The barrier layer prevents the hot melt adhesive being transported in the hose from discoloring and charring when the adhesive is heated from about 250° F. up to and including 450° F. for an extended period of time.Type: GrantFiled: June 25, 2017Date of Patent: July 9, 2024Assignee: Nordson CorporationInventors: Jim Keough, Leslie J.
