Wood-plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler.
Exterior wood-fiber composites like decks and rails haven't lived up to some of the early claims of long, maintenance-free life. In fact, composite decks with high wood loadings can shrink, expand, stain, warp, split, and fade much like natural.
