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.

Abstract: Formulated polyol compositions contain a terephthalic acid-based polyester polyol, a C4-7 hydrocarbon blowing agent, and a nonionic surfactant that has a hydrophilic-lipophilic balance of greater than 13 to 18.5. The formulated polyol compositions exhibit surprisingly good storage stability and resist stratifying into layers. The compositions are useful to make rigid polyurethane and/or polyisocyanurate foams. The good compatibility of the blowing agent leads to improved cell structure in the foams.
