| Abstract | Among the many industrial polymers, polyurethanes are known to exhibit versatile characteristics and wide applications. They are synthesized by reacting polyol (an alcohol with two or more reactive hydroxyl groups per molecule) with diisocyanate or a polymeric isocyanate in the presence / absence of suitable catalysts and additives. Polyurethanes can be prepared either by one-step or by prepolymer method. Due to the availability of different types of diisocyanates, polyols (polyester or polyether polyol with different molecular weight), chain extenders as well as methods of synthesis, a variety of polyurethanes can be produced leading to a broad spectrum of materials to meet specific applications. Polyurethanes are part of a diversified group of materials that find uses in a broad range of applications, both industrial and domestic such as foam mattresses, paints and lacquers, medical implants, rollers, electrical encapsulation, engineering components, shoe soles, seals and also in the mining industry (Clemiston 2008). |
