Urea formaldehyde-based resins have been the standard binders used to glue the particles together in many composite wood products, including particleboard, wheatboard, and medium density fiberboard (MDF). In recent years, however, concerns have been rising about the risks of cancer and bronchial health impacts from formaldehyde. Several market factors are driving major changes in the composition and technology of these resins. Pressure from the green building movement through market selection and certification programs, plus emissions regulations from the California Air Resources Board (CARB), are moving manufacturers to look for ways to reduce formaldehyde emissions or eliminate formaldehyde entirely from formulas.
