Abstract: Alkoxylated hydrophobes that include a poly(alkylene oxide) chain of at least 5 oxyalkylene units having a terminal secondary hydroxyl group or a terminal C1-8 hydrocarbyl group are effective internal mold release agents for epoxy resin moldings. The alkoxylated hydrophobe, when mixed with an epoxy resin, forms a mixture that is highly stable when heated to 80 to 100° C. and held at that temperature for a period of as much as 22 days.

Abstract: A continuous process for preparing insulation panels having thick (0.2 mm to 1 mm) metal facing panels and a fiber-reinforced polymer foam core is disclosed. In the process, a bottom metal facing panel is continuously supplied. A mat of reinforcing fibers and a foamable resin composition are applied to the bottom facing panel. A flexible barrier layer is applied atop the foamable resin composition, and the assembly is passed through nip rolls to compress the assembly and force the resin composition into the fiber mat. An adhesive layer and top metallic facing layer are then applied on top of the flexible barrier layer, and the resulting assembly is gauged and cured by passing it through a double band laminator.

Abstract: A continuous process for preparing insulation panels having thick (0.2 mm to 1 mm) metal facing panels and a fiber-reinforced polymer foam core is disclosed. In the process, a bottom metal facing panel (2) is continuously supplied. A mat (10) of reinforcing fibers and a foamable resin composition (19) are applied to the bottom facing panel. A flexible barrier layer (5) is applied atop the foamable resin composition, and the assembly is passed through nip rolls (12,13) to compress the assembly and force the resin composition into the fiber mat. An adhesive layer (4) and top metallic facing layer (1) are then applied on top of the flexible barrier layer, and the resulting assembly is gauged and cured by passing it through a double band laminator (11).

Abstract: Aerogel particles are impregnated with a volatile liquid. Organic polymer foams are made in the presence of the impregnated aerogel particles. The volatile liquid volatilizes during the foaming process, resulting in a composite foam in which the dispersed aerogel particle are filled with gas. The composite foams have exceptionally low thermal conductivities.
