WebProduction of Polyurethane Foam. Polyurethanes are produced by mixing two or more liquid streams. The polymer stream contains catalysts, surfactants, and blowing agents. These components are referred to as polyurethane systems. The isocyanate is also known as ‘A side’ and the blend of polyols is referred to as ‘B side’. Polyurethanes are produced by mixing two or more liquid streams. The polyol stream contains catalysts, surfactants, blowing agents (when making polyurethane foam insulation) and so on. The two components are referred to as a polyurethane system, or simply a system. The isocyanate is commonly referred to in North America as the 'A-side' or just the 'iso'. The blend of polyols and other additives is commonly referred to as the 'B-side' or as the 'poly'. This mixture might also be …
