What's the difference between chipboard and MDF?

The difference between particleboard and MDF (Medium Density Fibreboard) lies mainly in how they are manufactured, their properties and their uses. Particleboard is made from wood chips pressed together with glue under high pressure and heat. Less dense and strong than MDF, but sufficient for many furniture projects. MDF is made from very finely divided wood fibres mixed with glue, pressed into a dense board. More compact and stronger than particleboard, but heavier.
