  • Publication number: 20220032596
    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 TE1. 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 TE2 is applied to the surface of the rubber substrate to form a rubber substrate/film configuration. A compression force is applied at a temperature Tv (38° C.?TE2<Tv) 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 TL, wherein TE2<TL<TE1, 15° C.?(TE1?TL)?40° C., and 10° C.?(TL?TE2)?70° C., to form a vulcanized rubber-film/foam laminate.
