Abstract

A number of tacky polyurethane or other gel comprising composites are provided. The composites have foam carriers, which may be open cell, semi-open cell, reticulated or closed-cell foam. The tacky gel which, in one embodiment, may be polyurethane, typically comprising a thin surface coating on the foam gel and the foam is partially or fully saturated with the same gel comprising the thin surface layer of the foam. The skeletons may be included in the composite to provide additional structure integrity, and a moisture proof layer may be added to the top and/or bottom surfaces of the foam/gel.
