Wood plastic Composite Wall Board Decking
Wood Plastic Composite
The use of wood–plastic composite lumber in North America has experienced tremendous growth in the past decade, largely because of residential construction applications. Common applications in North America include decking, railings, window profiles, roof tiles, and siding. These lumber products are generally manufactured using profile extrusion. Some generalizations can be made regarding the performance of wood–plastic composites, but there are exceptions. Flexural and tensile properties of wood–plastic composite lumber generally fall between those of solid wood lumber and unfilled plastics. Most commercial wood–plastic composites are considerably less stiff than solid wood but are stiffer than unfilled plastic (Clemons 2002). Compared with solid wood lumber, wood–plastic composites have better decay resistance and dimensional stability when exposed to moisture. Compared with unfilled plastics, wood–plastic composites are stiffer and have better dimensional stability when exposed to changes in temperature.

In addition to these commercial deck products, wood–plastic composites are being developed for structural applications such as foundation elements, deck substructures, industrial decking, and shoreline structures (Bender and others 2006). In general, polyvinylcholoride and polyethylene formulations produce higher mechanical properties than those produced from polyethylene alone. Formulations that use coupling agents with either polypropylene or high-density polyethylene result in improved strength, stiffness, and reduced moisture absorption properties.
Properties of wood–plastic composites can vary greatly depending upon such variables as type, form, weight fractions of constituents, type of additives, and processing methods (Stark and Rowlands 2003, Wolcott and others 2006). Because formulations from each commercial manufacture are proprietary, design data should be obtained directly from the manufacturer.
