Polyurethanes (PU) are a general class of polymers prepared by the polyaddition of isocyanates and hydroxyl group containing compounds. PU s are formed via the reaction of poly-isocyanate and multi-functional hydroxyl compounds resulting in urethane linkages. The s are formed in wide range of densities and maybe flexible, semi-flexible or rigid in structure.
