摘要： Extruded polystyrene foams are made with an added brominated styrene-butadiene polymer as a flame retardant. The blowing agent is a mixture of carbon dioxide, ethanol and water, which may also contain a C4-C5 hydrocarbon. The blowing agent mixture overcomes a tendency of the brominated styrene-butadiene to form very small cells. This allows the foam to expand fully to form good quality, low density extruded foam.
