Description
A common name for an engineered wood product made from mixture of fine wood fibers and resin bonded together then comporessed into panels with smooth, flat surfaces at high temperature and pressure. Medium density fiberboard (MDF) panels are constructed from 82% wood fiber, 9% urea-formaldehyde resin and 1% paraffin wax. The density of the board, typically between 500-1000 kg/m3, is dependant on the type of fiber (softwood or hardwood) that is used. 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". In recent years, manufacturers have started using greener materials, such as non-toxic binders, and non-wood fibers (straw and bamboo).
Synonyms and Related Terms
Medium-density fiberboard; MDF; Medex®; Medite®; Medite II®
Personal Risks
When cut, MDF boards produce a large quantity of dust.
Collecction Risks
MDF products emit formaldehyde and other volatile organic compounds.
Working Properties
MDF boards are consistent in strength and size. They may be glued, doweled, painted or laminated and are dimensionally stable. Low -grade MDF may swell and break when saturated with water. Unsealed MDF may warp or expand in Humid environments.
