A joint research team in Al-Mustansiriyah and Middle Technical Universities conducted a study on designing a new program for simulating physical and chemical blowing agents to produce polyurethane foam. The study aimed at benefiting from the new designed program in reviewing the effect of mass balance on the blowing agent during the polymerization reaction of the polyurethane foam, estimating the remaining amount of foam gas and the ending amount in the foam cells, as well as calculating pressure of the blowing agent in the foam cells. The study recommended that this program can be adopted to estimate the efficacy of blowing agents, improve the performance of foam polymers and adopt new blowing agents.
