A catalyst is a compound used to affect the rate of a reaction from reactants to final product. Catalysts lower the activation energy required to achieve an excited molecular state, which allows the reaction to proceed more easily and with less energy. The primary job of the catalyst or combination of catalysts in a polyurethane reaction is to control the reaction profile. Polyurethane (PU) catalysts can be generally divided into two types, gelling catalysts and blowing catalysts. Gelling catalysts promote the reaction of the isocyanates with hydroxyl groups, and blowing catalysts are used in polyurethane foam systems and are more selective to catalyzing the reaction of the isocyanate with water to produce foam. This webinar is intended to give a fundamental overview of how PU catalysts work.
