Abstract
A composite material having a film operatively associated with a polyolefin foam layer and at least one metallic layer operatively associated with at least one of the foam layer and the film.
Claims28
A composite material comprising:
- a. a foam layer comprising polyolefin;
- b. a first film operatively associated with said foam layer;
- and
- c. at least one metallic layer operatively associated with at least one of said foam layer and said first film;
- wherein at least one edge of said first film extends beyond a corresponding edge of said foam layer.

A composite flooring material comprising:
- a. a foam layer comprising a polyolefin;
- b. a first film adhered to a first surface of the foam layer;
- c. a second film adhered to a second surface of the foam layer, wherein at least one edge of said second film extends beyond a corresponding edge of the foam layer;
- and
- d. a metallic layer operatively associated with at least one of said foam layer, said first film, and said second film.
2 more elements
A composite flooring material comprising:
- a. a foam layer comprising a polyolefin;
- and
- b. a metallic layer operatively associated with said foam layer, wherein at least one edge of said metallic layer extends beyond a corresponding edge of the foam layer.
A method for making a composite material comprising the steps of:
- a. operatively associating a film to surface of a foam layer such that at least one edge of said film extends beyond a corresponding edge of said foam layer;
- and
- b. operatively associating a metallic layer to at least one of said film and said foam layer.
