For aviation, railway, construction, sports and other aspects; Used for surface finishing of wooden furniture and metal; It is used for thermal insulation and cold preservation of storage tanks, pipelines, cold storages, beer, fermentation tanks and fresh-keeping barrels, thermal insulation and waterproof of buildings, and can also be used for prefabricated polyurethane plates; It can be used for manufacturing plastic products, wear-resistant synthetic rubber products, synthetic fibers, hard and soft foam plastic products, adhesives and coatings, etc. It is used for surface finishing of all kinds of woodwork, chemical equipment, telecommunications equipment and instruments and all kinds of transportation tools.
As a high molecular material with high strength, tear resistance and wear resistance, polyurethane resin is widely used in daily life, industrial and agricultural production, medicine and other fields.
Polyurethane elastomer is used as roller, conveyor belt, hose, automobile parts, sole, synthetic leather, wire and cable and medical artificial organs; Soft foam is used for vehicle, bedroom and clothing liner. Rigid foam is used for thermal insulation, sound absorption, packaging, insulation and low foaming synthetic wood. Coatings are used for advanced vehicles, furniture, wood and metal protection, pool dams and building leakage proof materials, and fabric coatings. The adhesive has good adhesion to metal, glass, ceramics, leather, fiber, etc. Besides, polyurethane can be made into emulsion, magnetic material and so on.
