  • Preparation of Liquid Isocyanurate-Modified Polymethylene Bis(Phenylisocyanate) Compositions of Controlled Viscosities
    Publication number: 20090105359
    Abstract: Disclosed is a method for the production of highly stable, liquid isocyanurate-modified PMDI compositions having relatively higher viscosity and a generally comparable functionality, as compared to conventional PMDI. An admixture of the isocyanurate-modified PMDI with conventional PMDI is suitable for use in the manufacture of a variety of polyurethane products, including rigid and flexible foams, coatings, elastomers and sealants. Foams produced using this admixture exhibit properties that are comparable to foams produced from standard polymeric MDI of comparable viscosity that don't contain isocyanurate moieties.
    Type: Application
