High productivity, low fugitive emission foams and foam processes |
摘要 |
A blowing agent for foaming polystyrene consisting essentially of at least one low permeability compound (preferably a volatile organic compound (VOC)), at least one low volatility compound (preferably a non-VOC) and, optionally, at least one high volatility compound (preferably a non-VOC). In one embodiment, the low permeability volatile organic compound is selected from the group consisting of isopentane and isobutane, the low volatility non-volatile organic compound is acetone and the high volatility non-volatile organic compound is carbon dioxide. The blowing agent of the present invention may be used to foam a polystyrene foam structure. The blowing agent is directed to achieving low fugitive VOC emissions.
