Most people mistake particle boards for MDF or fiberboards, and although they have a similar appearance, they are quite different. Particleboards are made of a mixture of sawdust, resin, and waste wood. These materials are subjected to heat and high pressure to make particle boards. They are cheaper compared to MDF and are widely used in kitchen countertops or floor underlayment. MDF or fiberboard, on the other hand, is more robust and more compact than particleboard. Its composition is similar to that of particleboards, but it has small particles of wood in place of wood dust. They are mostly used for high-end furniture and cabinets. The best part about MDF is that they are flexible and can be molded into different shapes.
