Durability of Wood Plastic CompositesDurability of wood plastic composites. wood-plastic composites (WPCs) are a combination of wood flour (or other natural materials such as rice husks) and plastic shaped into decking lumber. WPCs are a relatively new product and are often better known by their various brand names eg. , ChoiceDek, Eon or SmartDeck or as composite lumber. WPCs can be manufactured in a variety of colors, shapes and sizes, and with different surface textures. Lumber made entirely from ...
