ABSTRACT
One of the most rational methods of using secondary materials and waste is the production of composite materials based on them.
The technology of creation of decking on the basis of wood-plastic composite, consisting of surface and inner layer is presented in the article. The surface layer of the product is made from wood flour, polypropylene, impact resistance modifier and special additives. The inner layer consists of recycled thermoplastic polymer, filled with waste wood up to 10 mm.
The influence of the concentration of the species of wood filler on the water absorption and hardness of the samples as well as a group of combustibility of the product has been studied. Researches on the biological stability of floorings that show high resistance to the damaging action of microorganisms are presented. It was found that this construction material is practically non swells and absorbs little moisture in comparison with the analogues. The presence of the inner layer significantly increases the strength and reduces the final cost of the product compared with competing in these market segment materials.

Keywords: composite, wood filler, polymer, extrusion, water absorption
