Isocyanu rate Foams: Chemistry, Properties and Processing

The literature has become replete with references to the physical and mechanical properties of laboratory prepared isocyanurate foams and methods of modifying these products. Little attention has been given to the chemistry and mechanism of isocyanurate formation, or to methods of adopting this reaction to produce foams on a commercial scale. Accordingly, the purpose of this paper is to review the chemistry of isocyanurates and the mechanism for their formation. Also presented are general chemical formulations, physical properties and processing conditions for continuous lamination, bun, pour and spray applications. Typical physical properties of these low density isocyanurate foams, including laboratory flammability characteristics,

Polyisocyanurate Foams for Cryogenic, Petrochemical, and Solar Energy Applications

The use of polyisocyanurate foams as thermal insulation for cryogenic, petrochemical, and solar energy ap plications is discussed.
