Abstract

Methods of making molded articles and the articles formed by the method, particularly viscoelastic gel articles.

Claims

1. A molded article, comprising:

a thermoplastic elastomeric (TPE) barrier layer;

a fluid-permeable layer; and

a first polymerized gel layer disposed between and enclosed by the barrier layer and the fluid-permeable layer, wherein at least a portion of the first polymerized gel layer extends at least partially through the fluid-permeable layer.

2. The molded article of claim 1, further comprising a second layer of polymerized gel, wherein the first and second polymerized gel layers are at least partially interconnected through the fluid-permeable layer.

3. The molded article of claim 1, wherein the fluid-permeable layer is selected from the group consisting of synthetic and non-synthetic paper, knit fabrics, woven fabrics, non-woven fabrics, films, composites and/or combinations comprising at least one of the foregoing.

4. The molded article of claim 1, wherein the fluid-permeable layer comprises color, text, graphics, and combinations thereof.

5. The molded article of claim 1, wherein the barrier layer is a TPE film.

6. The molded article of claim 1, wherein the barrier layer comprises a support layer, and the TPE is disposed on the support layer, adjacent to the polymerized gel.

7. The molded article of claim 1, wherein the TPE film has an elongation ranging from about 100 percent to about 1500 percent.

8. The molded article of claim 1, wherein the TPE film has an elongation ranging from about 200 percent to about 1000 percent.

9. The molded article of claim 1, wherein the TPE film has an elongation ranging from about 300 percent to about 700 percent.

10. The molded article of claim 1, wherein the TPE film has a thickness ranging from about 0.2 milli-inch to about 5 milli-inch.

11. The molded article of claim 1, wherein the TPE film has a thickness ranging from about 0.5 milli-inch to about 3 milli-inch.

12. The molded article of claim 1, wherein the TPE film has a thickness ranging from about 0.6 milli-inch to about 2 milli-inch.

13. The molded article of claim 1, wherein the TPE is selected from the group consisting of thermoplastic polyurethane (TPU), silicone, and combinations comprising at least one of the foregoing.

14. The molded article of claim 1, wherein the barrier layer comprises an active agent.

15. The molded article of claim 14, wherein the active agent is selected from the group consisting of silver, tolnaftate, undecenoic acid, allylamines, chlorine, copper, baking soda, sodium omadine, zinc omadine, azoles, and combinations comprising at least one of the foregoing.

16. The molded article of claim 1, further comprising a manually releasable stabilizing layer disposed adjacent to the fluid-permeable layer, opposite the polymerized gel layer.

17. The molded article of claim 1, wherein the stabilizing layer comprises a thickness ranging from about 0.2 milli-inch to about 10 milli-inch.

18. The molded article of claim 1, wherein the stabilizing layer comprises a thickness ranging from about 0.5 milli-inch to about 5 milli-inch.

19. The molded article of claim 1, wherein the stabilizing layer comprises a thickness ranging from about 1 milli-inch to about 2 milli-inch.

20. The molded article of claim 1, wherein the first and second polymerized gel layers each comprise a hardness ranging from about 30 Shore 000 to about 88 Shore D.

21. The molded article of claim 1, wherein the first and second polymerized gel layers each comprise a hardness ranging from about 0.01 Shore 00 to about 70 Shore 00.

22. The molded article of claim 1, wherein the first and second polymerized gel layers each comprise a hardness ranging from about 30 Shore 000 to about 85 Shore 00.

23. The molded article of claim 1, wherein the polymerized gel layer comprises an adhesive strength sufficient to adhere to a surface.

24. The molded article of claim 1, wherein the polymerized gel layer comprises a polyurethane.

25. The molded article of claim 1, wherein the polymerized gel is transparent and the fluid-permeable layer comprises color, text, graphics, and combinations thereof.

26. The molded article of claim 1, wherein the polymerized layer and the stabilizing layer each comprise an adhesive strength, and the adhesive strength of the stabilizing layer is less than the adhesive strength of the polymerized layer.

27. The molded article of claim 26, comprising an adhesive material disposed on the stabilization layer and/or the fluid-permeable layer, between the stabilization and fluid-permeable layers.

28. The molded article of claim 1, further comprising a release agent disposed on one or both of the second polymerized gel layer and the stabilizing layer, between the second polymerized gel layer and the stabilizing layer.

29. The molded article of claim 1, wherein the barrier layer and/or the stabilizing layer comprise opposing surfaces, and a release agent is disposed on one or both of the opposing surfaces.

30. The molded article of claim 13, further comprising a release agent disposed on a surface of the barrier and/or stabilizing layers adjacent to the gel precursor.

31. The molded article of claim 2, further comprising a release agent disposed between the second polymerized gel layer and the stabilizing layer.

32. The molded article of claim 1, further comprising a flange extending from at least a portion of the perimeter of the molded article.

33. The molded article of claim 30, attached to a garment at the flange.

34. The molded article of claim 1, wherein the article is a self-adhesive article.

35. A molded article, comprising:
