Due to the presence of strong polar groups in the macromolecules of polyurethane, it possesses the following characteristics:

① Higher mechanical strength and oxidation stability.

② Offers high flexibility and resilience.

③ Excellent oil resistance, solvent resistance, water resistance, and fire resistance

Polyurethane is primarily used in the production of synthetic leather, polyurethane foam plastics, polyurethane coatings, polyurethane adhesives, polyurethane rubbers (elastomers), and polyurethane fibers. Additionally, polyurethane is employed in civil engineering, ground drilling, mining, and petroleum engineering, serving to seal water, stabilize buildings or subgrade; as a surfacing material, it is used for running tracks in sports fields and indoor floors in buildings.
