Abstract

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. 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 Tis applied to the surface of the rubber substrate to form a rubber substrate/film configuration. A compression force is applied at a temperature T(38° C.≤T<T) 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, wherein T<T<T, 15° C.≤(T−T)≤40° C., and 10° C.≤(T−T)≤70° C., to form a vulcanized rubber-film/foam laminate.
