The term of "composite" explaines the products which are made of two or more materials by bonding them with various glues. On the other hand the term of wood plastic composite is relatively new and is used to describe any material which is produced by gluing or joining of wooden material with other wooden material or the materials other than wood. In the forest product industry, although many different products made by joining small wooden particles, fibers or relatively larger pieces have various names, as a whole, during the last fifteen years, these materials have been described under the name of "wood composites. In this study, technological characteristics of the effects of different polymer materials used in the manufacture of wood polymer composites were investigated.
