Beschreibung
Zusammenfassung:	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. Se proporciona una manguera de transferencia de múltiples capas de adhesivo de fusión en caliente. La manguera de transferencia tiene una capa de barrera que impide o disminuye al mínimo el ingreso de oxígeno y otros gases en un conducto de la manguera. La manguera de transferencia tiene al menos una capa estructural que se superpone a una superficie externa de la capa de barrera para ayudar a la manguera a soportar una alta presión de fluido. La capa de barrera impide que el adhesivo de fusión en caliente que se transporta en la manguera se decolore y se carbonice cuando se calienta el adhesivo de aproximadamente 250°F (121.111°C) hasta, e incluyendo 450°F (232.22°C) durante un periodo de tiempo extendido.
