MDF (Medium Density Fiberboard) is typically a type of engineered wood made from wood fibers that are ground into a fine powder and then bonded together using adhesives or synthetic resins. MDF usually has the natural yellowish color of wood, with a smooth, even, and flat surface, but it is not moisture-resistant. Melamine is a decorative surface layer applied to MDF, offering high aesthetics with a wide variety of colors and finishes.
