Patent ID: 8426016

Claim:
A resilient composite structure comprising: a carrier layer of reticulated, open-cell, resilient polyurethane foam material, said resilient polyurethane foam material being substantially completely and uniformly impregnated with an impregnant comprising a curable silicone polymer and a filler; the impregnant being cured into a substantially elastomeric solid after said impregnation to produce a highly-durable, foamed, open-cell resilient composite structure wherein the impregnant partially coats the cell walls of the open cells of said carrier layer of resilient polyurethane foam material; wherein said impregnant has a viscosity in the range of about 10,000 cP/mPa's to about 12,000 cP/mPa's, being evenly distributed throughout the polyurethane foam material; and wherein said structure, after said silicone polymer is cured, is of a thickness that is less than an initial thickness of said carrier layer.
