Abstract: The present invention is an ornamental vinyl building article made up of a high-strength, extruded base molecularly bonded to a variable texture pattern layer. The variable texture pattern layer provides a highly representational and customizable surface appearance to the article, allowing it to mimic wood and stone building materials used for baseboards, panels, rails, moldings, carvings, friezes, and tiles. The extruded base includes polyvinyl chloride (PVC), nanoscale particles of chemically synthesized calcium carbonate, foaming agent, PVC plasticizer, lubricant, toughening agent, and thermal stabilizer. Once extruded, one surface of the extruded base is heated to allow a molecular bond interface to form between the extruded base and the variable texture pattern layer.

Abstract: The present invention is a non-toxic, highly representational vinyl flooring article made up of a high-strength substrate molecularly bonded to a variable texture pattern layer. The substrate is extruded from a vinyl composition of polyvinyl chloride (PVC), nanoscale particles of chemically synthesized calcium carbonate, foaming agent, PVC plasticizer, lubricant, toughening agent, and thermal stabilizer. None of the composition components are toxic. Once extruded, one surface of the substrate is heated to allow a molecular bond interface to form between the substrate and pattern layer. The variable texture pattern layer provides a highly representational and customizable surface appearance to the article.
