Chat Online1/1/2006· When used to build homes and other structures, expanded polystyrene beads are in fl ated using a pentane blowing agent and a fl ow of steam (Lee et al. 2005). Expanded polystyrene then forms the sandwiched core of panels that will eventually become the walls, roof and, if so desired, the fl oor of the structure.
Chat OnlinePentane plays a fundamental role in the production of polystyrene and polyurethane foams, serving as a blowing agent that helps to expand the raw plastic material and create the honeycomb structure within the foam that imparts excellent thermal properties. This makes these foams ideal for …
