Particle board is a three-layer wood-based board. It is made in the process of pressing a blend of wooden strands and synthetic resin at high temperature. The inner layer of the board is made of thick strands while the outer layers are made of fine strands, which give the board a smooth surface and ensure high mechanical parameters.

Surface is additionally sanded to allow further refining like melamine film coating.

Particle board shows excellent properties and it is widely used in the wood processing industry, especially in the furniture industry.
