  • Patent number: 10201911
    Abstract: A continuous process forms a unitary mat on a line having at least two conveyors spaced from each other. The process includes combining the isocyanate, an isocyanate catalyst, and a plurality of lignocellulosic particles to form a mixture and a self-polymerization product of the isocyanate in-situ in the mixture. The process also includes forming the unitary mat from the mixture on a first conveyer and transferring the unitary mat from the first conveyor to a second conveyor across a predetermined distance while maintaining structural integrity of the unitary mat. The lignocellulosic particles have a moisture content of 0.5 to 30 weight percent of water. Moreover, the continuous process is free of a step of adding water to the isocyanate, the isocyanate catalyst, the lignocellulosic particles, and/or the unitary mat.

  • Patent number: 7993736
    Abstract: A wood composite material comprises wood strands disposed in surface layers and one or more core layers, wherein about 70 wt % to about 98 wt % of the wood strands of the first and second surface layers are comprised of a wood species that has a density greater than a density of a wood species from which about 70 wt % to about 98 wt % of the strands in the one or more core layers are stranded.

  • Patent number: 7662457
    Abstract: Disclosed is a wood composite material comprising: wood strands disposed in surface layers and one or more core layers, whereby an intermediate density divides the wood strands so that the two surface layers of strands are more dense than the intermediate density, and the one or more core layers of the strands are less dense than the intermediate density, and wherein the core layer contains at least about 70 wt % of the strands that are less dense than the intermediate density; and the surface layers contain at least about 70 wt % of the strands that are more dense than the intermediate density.
