What is better MDF or particle board?

It depends on the specific application and your individual needs and preferences.

Medium-density fiberboard (MDF) is a type of engineered wood made from finely ground wood fibers that are combined with resin and heat-pressed to form panels. MDF is known for its uniform density, smooth surface, and ability to hold intricate shapes, which makes it a popular choice for cabinetry, furniture, and trim work.

Particleboard is another type of engineered wood product that is made from wood chips, sawdust, and other wood waste that is combined with resin and heat-pressed to form panels. Particleboard is less expensive than MDF and is often used for shelving, underlayment, and subfloors.

Both MDF and particleboard have their advantages and disadvantages, and the best choice depends on the specific use case. For example, MDF is more stable, uniform, and durable than particleboard, but it is also more expensive. Particleboard is less expensive and more widely available than MDF, but it is not as stable and can be more prone to warping, swelling, and cracking.

Ultimately, the choice between MDF and particleboard will come down to your budget, the specific project requirements, and your personal preferences.
