synergistic effects of physical blowing agents and chemical polyurethane foaming catalysts abstract: the production of polyurethane (pu) foam relies heavily on the controlled expansion of a reactive mixture, typically achieved through the use of blowing agents and catalysts. this article delves into the synergistic relationship between physical blowing agents (pbas) and chemical catalysts in pu...
