Polymer-fiber composite building material with bulk and aesthetically functional fillers

This is a building material made from plastic resin mixed with various powders and fibers. Some of these added ingredients, called bulk fillers, help reduce the amount of expensive plastic needed. Other ingredients, called aesthetically functional fillers, give the material its look and feel, such as color or texture. The claims specifically mention using materials like clay or talc for bulk fillers, and color or texture additives for aesthetics.
