Medium density fiberboard (MDF)

Description

A common dane for an engineered wood product made by combining wood fibers with an binder then forming into panels at high temperature and pressure. Medium density fiberboard (MDF) panels are constructed from an exterior-grade plywood core laminated on one or both surfaces with resin-treated fiberboard or paper (commonly called MDF). A thermosetting glue (such as a Phenolic resin) is used to adhered the MDF to the wood surface with heat and pressure. The fibrous laminate surface is smooth and opaque with resistance to scratches, peeling, cracking, and moisture. MDF boards are available in large sheets (4' x 8') in a variety of thicknesses, such as 3/8", 1/2", 5/8", 3/4" and 1". MDF's contain less adhesive than an MDO and is consider slightly weaker.
