Polyurethanes play an important role in our lives. Reducing energy consumption and producing goods with unusual shapes is the best reason for using polyurethane systems.
Polyurethane is the material resulting from the reaction of a polyol (an alcohol group with more than two reactive hydroxy groups in each molecule) with diisocyanate or polymeric isocyanate in the presence of catalysts and suitable additives. Despite the diversity in diisocyanate and spectrum A wide variety of polyols can produce many types of polyurethanes with various uses and properties.
