  • RIGID POLYURETHANE FOAMS COMPRISING A SILOXANE RICH NUCLEATING AGENT
    Publication number: 20220017717
    Abstract: The present technology provides a method of manufacturing a polyurethane foam having a low thermal conductivity from a foam formulation comprising a polyol, an isocyanate, a polyurethane catalyst, a surfactant, water, and a siloxane rich composition. The siloxane rich composition may act as a nucleating agent to reduce the cell size of the foams and may reduce its thermal conductivity.
