About MDF


MDF is a wood based composite. The primary constituent is a softwood which has been broken down into wood fibres; the very cells (tracheids, vessels, fibres and fibre-tracheids), which are far smaller entities than those used in particleboard. In Australia the main species used in the production of MDF is plantation grown radiata pine. A wide variety of softwood species will also constitute a suitable base for MDF production, though if too many species are used too great a variation in the properties of the finished MDF will result.

Other materials successfully used have been waste paper, randomly collected waste wood and bamboo. Mixing wood and other non-wood materials such as fibres of glass, steel, carbon and aramide have all resulted in successful MDF type products being produced.
