High productivity, low fugitive VOC emission foam process |
摘要 |
A blowing agent for foaming polystyrene consisting essentially of at least one low permeability volatile organic compound, at least one low volatility non-volatile organic compound and, optionally, at least one high volatility non-volatile organic compound. 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 volatile organic compounds (VOC) emissions.
