The Particle Boards are artificial wood made by damaging, dipping and grinding wood shavings, wood wool and timbering residue into wood pulp, mixing the pulp with glue, and then heat-pressing and drying the pulp. It is a type of manufactured wood made from compressed wood particles. Fine and strong, particleboard holds a screw better than plywood because it is denser and the material is not as vulnerable to expansion and contraction. Particle Boards are very efficient and useful.
