Blowing agent for the production of polystyrene. Polystyrene foam is traditionally produced with chlorofluorocarbon (CFC) blowing agents, contributing to ozone depletion in the stratosphere, ground-level ozone pollution, and climate change. Polystyrene foam is used in product packaging for insulation, stiffness, resistance to moisture, and recyclability. This novel production method uses carbon dioxide as a blowing agent to produce polystyrene. Carbon dioxide is a byproduct of several industrial processes. Carbon dioxide is accessible, inexpensive, and nonflammable.
