Polystyrene foam manufacturing process
WebInsulation. Insulation Materials. Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive and -- to a lesser degree -- convective heat flow in a building cavity. Rigid foam boards trap air or another ... WebThe process of producing expanded polystyrene foam (EPS) consists of three steps, each of which will be described separately below. Pre-expansion: To mold the parts, in the first stage, which is called pre-expansion, it is necessary to prepare the raw puffed material with the necessary density.
