Medium density fiberboard (MDF) |
 |
This sturdy, inexpensive substitute for wood is common in homes, though it's often hidden behind an attractive exterior. MDF is a composite material, made from wood fibers and adhesive. It is useful as a substrate material beneath laminate countertops, cabinets, and flooring, among other things. Because synthetic, formaldehyde-based resins are typically used in MDF, this material is a major source of formaldehyde offgassing in homes. Formaldehyde-free MDF products are available. |
