Polyurethane, which is a polyurethane containing a urethane group in the main chain of the macromolecule, is called polyurethane. Polyurethane is classified into two types: polyester polyurethane and polyether polyurethane. Polyurethane has many excellent properties, so it has a wide range of uses. It has high mechanical strength and oxidative stability and has high flexibility and resilience and excellent oil resistance, solvent resistance, water resistance and fire resistance.
