The Effects of Some Synthetic Adhesives on the Formaldehyde Emission of the Particleboard

The formaldehyde emission is the one of the major problems of the particleboard industry that harms to human health and environment. The purpose of this study was to determine the effect of the adhesive type on the formaldehyde emission of three-layered particleboard. The urea formaldehyde (UF), phenol formaldehyde (PF) and melamine-urea formaldehyde (MUF) adhesives were used as adhesives. Black poplar (Populus nigra) was used as wood raw material. The panels produced with PF and MUF adhesives had the required level of formaldehyde emission value specified in EN 312-2 (1996) and these panels could be classified as E-1 grade particleboard. The particleboard samples produced with UF adhesive had more than the formaldehyde emission value required for E-1 class particleboards.
