MDF, or Medium-Density Fiberboard, is a type of engineered wood product made from wood fibers or other plant-based fibers. The manufacturing process involves breaking down raw materials into fine fibers, which are then dried and mixed with adhesives such as urea-formaldehyde resin or other suitable bonding agents. After this, the mixture is pressed under high heat and pressure to form dense panels. MDF is known for its uniform texture and smooth surface, making it ideal for furniture, cabinetry, and interior design applications. The density of MDF typically ranges between 0.5 and 0.8 grams per cubic centimeter, and the thickness can vary from 3 mm to 30 mm, depending on the intended use. Compared to particle board, MDF offers better strength and a more consistent finish, though it is heavier and less moisture-resistant. It is widely used in both residential and commercial settings due to its versatility and affordability.
