Polyurethanes (PUs) are a class of versatile materials with great potential for use in different applications. They are used in the manufacture of many different items, such as paints, liquid coatings, elastomers, insulators, elastics, foams and integral skins. Polyurethanes are produced by polymerization of a diisocyanate with a polyol.
Vaisala K-PATENTS® Process Refractometer PR-43-GP provides accurate and reliable refractive index measurement for different applications in the production of isocyanates and PU. The refractometer can be installed directly in the polymerization reactor to monitor continuously the progress of the reaction.
