Wood Plastic Composites (WPC) Markets in North America, Japan

WPC are thermoplastically processible composites made from the renewable resource wood, mostly synthetic plastics and additives. A typical WPC product for example is an extruded profile for a veranda decking, consisting of 70% wood flour, 25% polyethylene or polypropylene and 5% additives such as bonding agents,

Wood-Plastic Composites - Fraunhofer WKI

WPC consist predominantly of a lignocellulosic component in a proportion of up to 70 percent by mass, a thermoplastically-processable polymer of up to 50 percent by mass, a bonding agent and other additives such as pigments, light stabilizers or lubricants. For their manufacture, processing procedures for plastics are
