Abstract

This invention relates to tiles that are suitable directly for use in flooring, on bathroom and other walls, kitchen and bath countertops, table tops etc. The tile is composed of at least two layers. One layer is made essentially entirely of, or includes, high impact polystyrene foam. The other layer can be made of, or include, any thermoplastic polymer.

Claims

1. A tile comprising:

a first layer comprising foamed, high impact polystyrene; and

a second layer comprising a thermoplastic polymer.

2. The tile of claim 1 wherein at least one of the layers is melt extruded.

3. The tile of claim 1 wherein the two layers are adhered to one another by melt extrusion.

4. The tile of claim 1 further comprising a tie layer and/or a barrier layer.

5. The tile of claim 1 having a surface area no larger than 256 in².

6. The tile of claim 1 wherein the second layer is colorable.

7. The tile of claim 1 wherein the second layer is colored.

8. The tile of claim 1 wherein the high impact polystyrene has a notched Izod impact value at 73°

F. as determined according to ASTM D-256 of at least 0.85 ft-lb/in.

9. The tile of claim 1 wherein the second layer has been chemically or mechanically manipulated to impart texture and/or gloss and/or to remove gloss.

10. The tile of claim 1 wherein the foam comprises expanded microspheres.

11. A tile comprising:

a first layer consisting essentially of foamed, high impact polystyrene; and

a second layer.

12. The tile of claim 11 wherein at least one of the layers is melt extruded.

13. The tile of claim 11 further comprising a tie layer or a barrier layer.

14. The tile of claim 11 having a surface area no larger than 256 in².

15. The tile of claim 11 wherein the second layer is colorable.

16. The tile of claim 11 wherein the second layer is colored.

17. The tile of claim 11 wherein the high impact polystyrene has a notched Izod impact value at 73°

F. as determined according to ASTM D-256 of at least 0.85 ft-lb/in.

18. The tile of claim 11 wherein the second layer has been chemically or mechanically manipulated to impart texture and/or gloss and/or to remove gloss.

19. The tile of claim 11 wherein the foam comprises expanded microspheres.

20. A tile consisting essentially of:

a first layer comprising foamed, high impact polystyrene; and

a second layer comprising a thermoplastic polymer.

21. The tile of claim 20 wherein at least one of the layers is melt extruded.

22. The tile of claim 20 further comprising a tie layer and/or a barrier layer.

23. The tile of claim 20 having a surface area no larger than 256 in².

24. The tile of claim 20 wherein the second layer is colorable.

25. The tile of claim 20 wherein the second layer is colored.

26. The tile of claim 20 wherein the high impact polystyrene has a notched Izod impact value at 73°

F. as determined according to ASTM D-256 of at least 0.85 ft-lb/in.

27. The tile of claim 20 wherein the second layer has been chemically or mechanically manipulated to impart texture and/or gloss and/or to remove gloss.
