Wood-plastic composites (WPCs) are composite materials made of wood fiber / wood flour and thermoplastic(s) (includes PE, PP, PVC etc.). Chemical additives seem practically invisible (except mineral fillers and pigments, if added) in the composite structure.
Most composite lumber is a mixture of recycled plastic (about 30%-50%) and wood fibers; it is advertised as a low-maintenance, long-lasting (typically with a 10-25 year warranty), splinter-free material that resists rot, insects and UV rays.
