Particle board is an engineered wood product made from wood chips, sawmill shavings, or even sawdust, which are bonded together with a synthetic resin or other binder under heat and pressure. It is commonly used in furniture, cabinetry, and flooring due to its affordability and smooth surface, which can be laminated or veneered for decorative purposes. However, it is less durable and water-resistant compared to plywood or solid wood.
