Here is the answer…Both MDF and particleboard are building materials made from crushed wood chips or shavings mixed with adhesives and compressed.Particleboard is a board made of small pieces of wood, with the wood chips visible in the photo above. On the other hand, MDF (medium-density fiberboard) is a board made from wood chips and other plant materials that are further fiberizing and molded.MDF is a product with a density of 0.35 g/㎤ or greater that has undergone a dry process (processing without water).
