ABSTRACT:
An inventive laminate is provided useful in forming inflatable articles, such as rafts and kayaks, automobile safety bags, air craft and life saving jackets/vests, diving buoyancy compensator vests, medical therapeutic containers, waders, packaging material, inflatable boots and soles, inflatable shoes and soles, and the like. The laminate includes an elastomer layer capable of repeated two-dimensional stretch and retraction. Opposed to the elastomer layer is a first substantially gas impermeable layer. The two layers are substantially continuously adhered to one another and maintained in laminated form. Products formed from the laminate can be repeatedly stretched and retract to accommodate substantial volume increases due to elastic deformations in response to elevated pressures. Because the laminate is elastically deformable, lower inflation pressures can be used in inflatable clothing articles, such as buoyancy compensators, which results in a more comfortable garment.
