Polyurethane Industry


Polyurethane

  • Chemically speaking polyurethane is a polymer containing carbamate or urethane linkage (-NHCOO) formed by reaction of isocyanate with polyol as follows;

    In practice, polyurethane is a mixture of compounds containing urethane, urea, isocyanurate, allophanates etc. depending upon the starting raw materials and their reactions.

  • Polyurethane offers unique properties like good abrasion resistance, wear resistance, elongation, resilience, flexibility, scratch resistance mechanical strength, adhesion, low temperature flexibility, thermal insulation and electrical insulation etc.. Polyurethane is one of the very few polymers which is available in wide range of hardness and shows properties of thermoset, thermoplastics and elastomers. Due to these range of properties and forms, it finds applications in rigid and flexible foam, fiber, film, composites, elastomers, coatings, adhesives.

    Global market share of each of these segments is as follows;
