Polyurethane/polyisocyanurate foam insulation described herein is derived from a composition that contains an organic polyisocyanate, an isocyanate reactive material containing at least about 20% by weight, based on the total weight of the composition, of an aromatic polyester polyol, a hydrocarbon blowing agent, a first catalyst selected from the group consisting of a carboxylate salt of an alkali metal, a carboxylate salt of an alkaline earth metal, a carboxylate salt of a quaternary ammonium, and combinations thereof, and a second catalyst comprising a non-reactive tertiary amine, wherein a molar ratio of the first catalyst to the second catalyst is less than about 1.25, the composition gels quickly, and the composition has an isocyanate index greater than about 175. Such an insulating foam has a ratio of thermal conductivity at 75&#xb0; F. to thermal conductivity at 25&#xb0; F. between about 0.98 and about 1.10.

Hydrocarbon blown polyurethane foam formulation giving desirable thermal insulation properties

Adhesives, reaction systems, and processes for the production of lignocellulosic composites. The reaction system comprises a multi-component adhesive and a lignocellulosic substrate. The lignocellulosic substrate comprises a plurality of lignocellulosic adherends and is preferably a mass of wood particles. The multi-component adhesive comprises a multi-functional isocyanate, a hydrophilic polyahl, and an organotransition metal catalyst. The multi-component adhesive is characterized by being formulated into at least two mutually reactive chemical component streams. The process comprises the separate application of the mutually reactive chemical component streams of the multi-component adhesive to the lignocellulosic substrate, followed by forming and pressing the adhesive treated substrate under conditions appropriate for curing the adhesive and forming a lignocellulosic composite article. The adhesives, reaction systems, and processes are particularly well suited for the production of oriented strand board (OSB).
