Bonding method to attach ethylene-based polymer foam with vulcanized rubber
A process of adhering a foam structure to a rubber substrate is provided. The foam structure is composed of a first composition comprising a first ethylene-based polymer having a peak melting temperature T.sub.E1. A film composed of a second composition comprising a second ethylene-based polymer having a melt index≤10 g/10 min and a peak melting temperature T.sub.E2 is applied to the surface of the rubber substrate to form a rubber substrate/film configuration. A compression force is applied at a temperature T.sub.v (38° C.≤T.sub.E2<T.sub.v) to form a vulcanized rubber/film laminate. The foam structure is applied to a surface of the film of the vulcanized rubber/film laminate to form a vulcanized rubber-film laminate/foam configuration. A compression force is applied at a temperature T.sub.L, wherein T.sub.E2<T.sub.L<T.sub.E1, 15° C.≤(T.sub.E1−T.sub.L)≤40° C., and 10° C.≤(T.sub.L−T.sub.E2)≤70° C., to form a vulcanized rubber-film/foam laminate.

A tensile component is disposed in the interior cavity and includes tensile layers and a plurality of tethers connecting the tensile layers. The tensile layers are connected to an inner surface of the bladder such that the tethers span across the interior cavity. The bladder has an inwardly-protruding bond that joins an inner surface of the bladder to the tensile component, protrudes inward into the interior cavity, and partially traverses the plurality of tethers such that the bladder is narrowed at the inwardly protruding bond and the gas in the interior cavity fluidly communicates across the inwardly-protruding bond. A method of manufacturing a cushioning article is disclosed.
CUSHIONING ARTICLE WITH TENSILE COMPONENT AND METHOD OF MANUFACTURING A CUSHIONING ARTICLE
A cushioning article comprises a first and a second polymeric sheet bonded to one another and enclosing an interior cavity. The polymeric sheets retain a gas in the interior cavity. A tensile component disposed in the interior cavity includes a first tensile layer, a second tensile layer, and a plurality of tethers spanning the interior cavity and connecting the first tensile layer to the second tensile layer. An inwardly-protruding bond joins the first polymeric sheet to the first tensile layer, protrudes inward from the first polymeric sheet toward the second polymeric sheet, and partially traverses the plurality of tethers. The first polymeric sheet is displaced from the first tensile layer adjacent to the inwardly-protruding bond by the gas. A method of manufacturing a cushioning article is disclosed.
