| titleOfInvention | Foam structure with an inorganic blowing agent |
| abstract | A melt polymer material for afoam structure, e.g. insulation board, comprises 80% to 98% by weight of a styrenic polymer, preferably polystyrene; 1% to 10% by weight of a low molecular weight random styrene butadiene copolymer resin; and 1% to 10% by weight of an inorganic blowing agent, preferably carbon dioxide. The low molecular weight random styrene butadiene copolymer resin comprises 80% to 95% by weight styrene and 5% to 20% by weight butadiene; has a weight average molecular weight of 100,000 to 140,000; and a molecular weight distribution (MWD) of 2.0 to 8.0. A process for making the foam structure involves heating the styrenic polymer and mixing the random styrene butadiene copolymer resin and the blowing agent into the styrenic polymer, and then molding the resultant mixture. The foam structure generally is closed-cell; has an average cell size of 300 microns (0.3 millimeters); a density between 20 g/l and 45 g/ml; and if insulation board, measures 1 meter wide up to 100 millimeters thick. |
