Abstract
Methods of making molded articles and the articles formed by the method, particularly viscoelastic gel articles.
Claims26
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.

A method of molding an article, comprising:
- selecting a first mold section comprising an upper surface, the upper surface comprising a recessed region, and the recessed region comprising a plurality of mold units disposed therein;
- disposing a barrier layer onto the upper surface of the first mold section, the barrier layer comprising a thermoplastic elastomeric (TPE) material;
- dispensing a first portion of a gel precursor onto the barrier layer;
- disposing a fluid-permeable material layer over the gel precursor;
- disposing a stabilizing layer over the fluid-permeable material layer and forming an interface between the gel precursor and the fluid-permeable material layer;
- advancing the interface while applying pressure to the stabilizing layer adjacent to the interface, until the gel precursor is covered by the fluid-permeable material layer;
- closing the mold;
- allowing the gel precursor to cure;
- and
- removing a sheet comprising a plurality of molded articles interconnected by a layer of polymerized gel.
