Abstract: It has been found that in addition to acting as an auxiliary blowing agent, various salts of formic acid may be used to tailor the reactivity characteristics of rigid, polyurethane foam formulation. Salts of particular interest are: ammonium formate, sodium formate, and potassium formate. By varying amounts and combinations of the above salts, characteristics of a formulation's reactivity such as cream time, gel time, rise time, and tack-free time may be manipulated.
