What is better MDF or particle board?

MDF (Medium-density fiberboard) and particleboard are both engineered wood products, but they have some differences that make one better suited for certain applications than the other.

MDF is made by breaking down hardwood or softwood residuals into fibers, which are then combined with wax and resin binders under heat and pressure. MDF is smoother, denser and more uniform than particleboard, making it a popular choice for furniture, cabinetry, millwork and musical instruments. It also takes paint and finishes well and does not shrink or swell much with changes in humidity. However, MDF is more expensive and heavier than particleboard and not as strong or durable.

Particleboard, on the other hand, is made from larger wood chips, sawdust and shavings that are combined with resin and compressed under high pressure. Particleboard is a low-cost alternative to solid wood and MDF, but it is less dense, less uniform and less smooth, with visible chip and knot defects. Particleboard also swells and shrinks more than MDF with changes in humidity, and it is not as strong or moisture-resistant. Particleboard is often used in applications where weight and cost are important, such as shelving, floor underlayment, and as a substrate for laminates and veneers.

In summary, MDF is a better choice for applications where appearance and uniformity are important, while particleboard is better suited for applications where cost and weight are the main concerns.
