The mechanical, physical properties and decay resistances of particleboard made from particles impregnated with Pinus brutia bark
extractives were examined. Properties included were modulus of rupture, modulus of elasticity, internal bond, thickness swelling, and
weight loss according to European standards. The results showed that particleboards made from particles impregnated with bark extractives
had signiWcantly lower mechanical values than those made from unimpregnated particles. Impregnating wood particles with bark
extractives improved the decay resistance and thickness swelling of particleboard. Increasing concentration of the extractives decreased
the mechanical properties and improved the thickness swelling and decay resistance of the panels. Particleboards made from 1% P. brutia
bark extractives met the speciWcations for modulus of rupture and internal bond strength for general purposes.
