  • Publication number: 20260103578
    Abstract: The present disclosure provides a method to produce a froth polyurethane foam using storage stable components. The method comprises preparing an A component, which comprises an isocyanate; preparing a B component, which comprises an isocyanate-reactive compound, and generating a foam by mixing the A component and the B component at a low pressure; wherein the A component or the B component or both further comprise a blowing agent comprising E-1,1,1,4,4,4-hexafluoro-2-butene (E-HFO-1336mzz) and one or more of a co-blowing agent chosen from carbon dioxide, nitrogen, or 1,1-difluoroethane (HFC-152a).
