ABSTRACT:
Wood products of superior strength are produced from wood particulates that have been extracted with a solvent to remove volatile organic compounds and a significant proportion of pitch from the wood particulates. The products are especially resistant to weakening caused by water immersion. As a consequence of the enhanced strength and stiffness of the composites, wood products may be made thinner, and of lighter weight, for the same equivalent strength and stiffness at lower cost. The process of drying the particulate raw material and forming the composite wood products, by subjecting to heat and pressure, are virtually free from emissions of volatile organic compounds into the environment.
