Particle board
pressed wood board / From Wikipedia, the free encyclopedia
Particle board, also known as particleboard and chipboard, is a wood product made from chips of wood or sawdust. It is mixed with resin or glue (both adhesives), then, under pressure and heat, pressed into uniform sheets.[1] Particle board is used in building construction and furniture making. It is cheaper to make than plywood but not as strong. Type 1 particle board expands when exposed to moisture. For that reason it is not usually recommended to be used outdoors.[2] Type 2 particle board uses waterproof glues and can be used outdoors.[2]
