Polyurethane rubber (AU-polyester urethane, EU-polyether urethane) is a thermoplastic elastomer formed by reacting a polyol with a disocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethane rubber is widely used due to its high strength, and excellent tear and abrasion resistance. Polyurethane also provides excellent permeation resistance.
