发明名称 POLYURETHANE FOAM PAD AND METHODS OF MAKING AND USING SAME
摘要 Disclosed are polyurethane foam pads and methods of making and using same. Also disclosed are processes for making the foam pads, and methods of using the foam pads. The polyurethane foam pad comprises a cured polyurethane foam layer having a first surface and an opposed second surface, wherein the polyurethane foam is formed from a mechanically frothed and chemically blown polyurethane composition; a backing layer contacting to the first surface of the cured polyurethane foam layer; and a film layer affixed to the second surface of the cured polyurethane foam layer; wherein the laminate polyurethane foam pad is not attached to a pre-manufactured floor covering. The process for preparing the polyurethane foam pad comprises providing an uncured foamable polyurethane composition; applying the foamable polyurethane composition to a surface of a backing material; metering the applied polyurethane composition to form a substantially uniform layer of the uncured polyurethane composition having a predetermined thickness; applying a top layer to the polyurethane composition layer; and curing the foamable polyurethane composition; wherein the composite polyurethane foam pad is not attached to a pre-manufactured floor covering.
