Particle Board, also called as medium density fibreboard (MDF) is manufactured from wood pulp, saw mill chips, sawdust with synthetic resins or any suitable binders. These boards are cheaper, denser and uniform than conventional wood and plywood. These are substituted when there is less requirement of strength or appearance are needed. Nowadays, these boards are painted attractively. A major disadvantage of particleboard is that it is very prone to expansion and discoloration due to moisture, particularly when it is not covered with paint.
