  • Publication number: 20140079941
    Abstract: Disclosed are foam compositions and processes to form closed-cell phenolic foams. The foams comprises a continuous polymeric phase defining a plurality of cells, wherein the continuous polymeric phase comprises a phenol-formaldehyde resole derived from a phenol and formaldehyde, and wherein the plurality of cells comprises a plurality of open-cells and a plurality of closed-cells with an open-cell content measured according to ASTM D6226-5, of less than 50%. The foam composition also comprises a discontinuous phase disposed in at least a portion of the plurality of closed-cells, the discontinuous phase comprising 1,1,1,4,4,4-hexafluoro-2-butene.
