"What are WPC Materials? Wood plastic composite materials, or WPCs, combine thermoplastic materials, such as PVC, polyethylene, or polypropylene, with natural fibers, such as wood. Compared to the thermoplastic in the compound, WPCs have: 1, a significantly lower coefficient of thermal expansion, 2, a higher heat deflection temperature, and 3, a higher modulus of elasticity. WPCs are an excellent choice for outdoor applications that withstand varying weather conditions, temperature ranges, and other environmental exposures. WPCs are also resistant to rot, decay, and insects. These materials have been used in products for decades in both the United States and Europe and are a proven solution for several industries including fenestration (windows, entry doors, and patio doors), garage door, fencing, trim and molding, railing, decking, and spas. To ensure the best fit for your application, WPCs can be custom formulated to consider the properties and specifications most important to you. Your custom formulation can be extruded into custom shapes (or profiles), including complex, hollow products. Profiles can be embossed with wood grain or other custom textures, and/or they can be extruded with other materials (including flexible materials or custom colored capstocks) to provide functional and aesthetic advantages. For those products requiring additional fabrication or machining, standard tools can be used. Some WPCs can be painted or stained with consumer available products, which provides flexibility and an aesthetic advantage most thermoplastic materials alone cannot offer. WPC products are also lower maintenance than many other options available today. WPCs are environmentally friendly and recyclable."
