WPC is a new class of materials for both the plastic and wood industries, as it represents an integration technology of these two sectors of the economy.Finishing and structural materials of wood-polymer composite WPC, used in industrial and civil construction, agriculture, in the reconstruction of buildings and structures for various purposes.Wood-polymer composite materials-artificial multi-component materials consisting of wood structural elements connected to each other by a polymer matrix, including, if necessary, other chemical additives and physical structural elements. Wood-polymer composite is a material consisting of wood fibers from 50% to 80%, polymer matrix from 15% to 50% and additives (additives) from 2% to 8%.
