ADHESIVE TRANSFER HOSE HAVING A BARRIER LAYER AND METHOD OF USE

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 beingtransported in the hose from discoloring and charring when the adhesive is heated from about 250 DEG F. up to and including 450 DEG F. for an extended period of time. 提供了具有屏障层的粘合剂传输软管和使用方法。该粘合剂传输软管是多层热熔粘合剂传输软管。传输软管具有屏障层，屏障层防止或最小化氧气和其他气体进入到软管的导管中。传输软管具有包覆屏障层的外表面的至少个结构层，以有助于软管耐受高流体压力。当在软管内运输的热熔粘合剂在延长的时段内被加热到从大约250℉直至且包括450℉时，屏障层防止该粘合剂变色和结焦。
