For the manufacturer interested in a knowledgeable source for polyurethane components, Upjohn Polymer Chemicals also offers specialty polyols, catalysts, and formulated chemicals for use with the PAPIs and Isonates. IsonoPis the trade name of Upjohn's polyols; they are avail able for use with specific PAPIs in the production of refrigeration, lamination, and block foam and with specific Isonates for polyether and polyester shoe soling systems as well as in reaction in jection molding.The Upjohn cat alysts are called Curithane®and are used in the production of isocyanurate foams. Upjohn Polymer Chemicals has also expanded the use of MDI in the rapidly developing field of isocyanate-based polymers polyisocyanurates, both cellular and noncellular. For further information on these and other Upjohn products and on their many applications, please write or call Upjohn Polymer Chemicals Division: P.O. Box 685 LaPorte, Texas 77571 (713)479-1541
