Abstract
A composite article includes a first zone made entirely of plastic and a second zone made of plastic and natural fiber. The first and second zones are integral and are continuously coextruded. The ratio of natural fiber in the second zone is between 10% and 55%. The outer surface of the second zone includes embossing to resemble wood grain. The outer surface has sufficient porosity so as to hold and retain wood stain and paint so that the composite article is stainable to resemble genuine wood. The composition of the second zone includes between 45% and 90% polyvinylchloride, between 10% and 55% natural fiber, and external lubricate and a fusion enhancer. A color adjusting agent such as titanium dioxide, and coloring agents may also be added.
