Abstract: The present invention provides a sheet of polymeric foam comprising chemically cross-linked, closed-cell, foam comprising at least one polyolefin; cork particles dispersed within said polymeric foam wherein said foam has a specific gravity of between 40-250 kg/m3 and is essentially free of visible perforations. Also provided by the present invention is a process for producing a continuous polymeric sheet said comprising a chemically cross-linked, closed-cell, polyolefin foam comprising at least one polyolefin and cork particles, homogenously dispersed within the polyolefin foam wherein once produced, said continuous polymeric sheet has a specific gravity of between 40-250 kg/m3 and is essentially free of visible perforations; the process comprising (i) continuously feeding into a mixing arrangement set at a temperature of between 60° C. and 200° C.

Abstract: A polymeric sheet comprising: a first surface and a second surface; and a first embossed pattern on at least one of the first surface or the second surface and method of preparing same is provided. In one aspect, the sheet comprises at least two protrusions, the at least two protrusions direct, impede, and/or control gas movement between the at least two protrusions when arranged in contact with a surface and externally compressed. In another aspect, the sheet is at least partially cross-linked and/or foamed.
