Process for producing polyurethane or polyisocyanurate foam construction board
A recently granted patent (Publication Number: US11999833B2) outlines a process for producing polyurethane or polyisocyanurate foam construction boards. The process involves combining specific reactant streams, including polymeric MDI and aromatic polyester polyol, along with surfactants, flame retardants, catalysts, and a physical blowing agent mixture. The resulting closed-cell foam has a density ranging from 1.5 to 1.8 lbs/ft3 and an index of at least 210. Additional steps may include exposing the reaction mixture to heat, depositing it onto a facer, and processing it within a laminator to produce construction boards with specific properties.
Furthermore, the patent describes an alternative process for producing polyurethane or polyisocyanurate construction boards by combining polyester polyol, isocyanate, and a physical blowing agent mixture containing isopentane, n-pentane, and methyl formate. This mixture, with specific ratios and components, results in a closed-cell foam with a density of 1.0 to 2.5 lbs/ft3 and an index of at least 210. The process involves depositing the foam-forming mixture on a facer and heating it to form the closed-cell foam. The physical blowing agent mixture includes a specific percentage of methyl formate, contributing to the desired properties of the foam. These patented processes offer a detailed method for producing foam construction boards with controlled density, index, and other key characteristics.
