Abstract:

Disclosed in one aspect is an anti-skid sheet comprising at least one contact layer selected from the group consisting of dynamically vulcanized alloys, propylene-α-olefin copolymers, and blends thereof; and at least one substrate layer comprising polyethylene having a density of from greater than 0. 935 g/cm. In one embodiment, the dynamically vulcanized alloy comprises a blend of one or more polyolefins and an at least partially vulcanized rubber. Disclosed in another aspect is a method of forming the anti-skid sheet comprising providing a melt-blending extruder for each of the sheet layers, at least one substrate layer as disclosed herein and at least one contact layer as disclosed herein, and co-extruding a melt of each component to form a co-extruded sheet. In a particular embodiment, the anti-skid sheet is thermoformed to form an article.
