Currently, wood flour consisting of small wood particles with low aspect ratio is used as the main wood raw material in commercial wood-plastic composites. A better reinforcement is achieved by using wood fibers with a higher aspect ratio, but individual fibers are seldom used in composite manufacturing due to processing problems and higher cost.

 · Prepare and Mix Ingredients. The wood flour used in WPCs has to contain far less moisture than one would find in nature, so before going into the hopper, it gets heated and dried until it's almost free of water. At the same time, the plastic–which looks like soap flakes–is heated to a liquid state. (That's why it's typically called "resin.")

Wood Plastic Composites

wood flour as a filler in plastics. Wood flour is made com-mercially by grinding postindustrial material, such as planer shavings, chips, and sawdust, into a fine, flour-like consistency. Wood fiber, although more difficult to process than wood flour, can lead to superior composite properties and act more as a reinforcement than as a filler.
