Abstract:
Chemically embossed foamed plastic sheet, and method of producing it, which sheet is formed of a base layer of fused resin particles, such as PVC, randomly intermixed with particles of a foaming inhibitor, especially benzotriazole; and an upper layer of foamed plastic, such as PVC, having irregularly shaped, lump-like elevated areas interspersed with irregularly shaped, trough-like depressions. The depressions result from the inhibiting action of foaming inhibitor particles in the base layer upon the blowing agent used for expanding the foamed layer. In the Example, the foamed layer is pigmented PVC with a gloss surface, lying in rectangular patches upon the base layer; and the base layer is fused pigmented PVC intermixed with particles of benzotriazole giving it a grainy texture.
