Methods of making polymeric articles and polymeric articles formed thereby
Methods of making molded articles and the articles formed by the method, particularly viscoelastic gel articles.
1. A self-adhesive shoe insert, 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 shoe insert 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 shoe insert of claim 1 , wherein the first 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 shoe insert 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.
5. The shoe insert of claim 1 , further comprising a manually releasable stabilizing layer disposed adjacent to the fluid-permeable layer, opposite the polymerized gel layer.
6. The shoe insert of claim 2 , further comprising a release agent disposed between the second polymerized gel layer and the stabilizing layer.
7. The shoe insert 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.
8. The shoe insert of claim 1 , wherein the gel comprises an active agent disposed in the barrier layer, and 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.
9. The shoe insert of claim 1 , wherein the polymerized gel layer comprises an adhesive strength sufficient to adhere to the inner surface of a shoe.
10. The shoe insert of claim 1 , wherein the polymerized gel layer comprises a thermoplastic polyurethane.
11. The shoe insert of claim 1 , wherein the first and second polymerized gel layers each comprise a hardness ranging from about 30 Shore 000 to about 75 Shore 00.
12. The shoe insert of claim 1 , wherein the polymerized gel is transparent and the fluid-permeable layer comprises color, text, graphics, and combinations thereof.
