Introduction: Polyurethane is a type of polymer with a - NHCOO - repeating structural unit in its main chain. The abbreviation PU in English. It is polymerized from isocyanates (monomers) and hydroxyl compounds. Due to its strong polar amino ester group, it is insoluble in non-polar groups and has good oil resistance, toughness, wear resistance, aging resistance, and adhesion. Materials that can adapt to a wide temperature range (-50~150 ºC) can be produced using different raw materials, including elastomers, thermoplastic resins, and thermosetting resins. Usage: used for manufacturing various walking wheels, rubber rollers, rubber rods, rubber plates, sealing elements, etc. Used for finishing of wool, silk, cotton and blended fabrics, knitted fleece fabrics, medium length wool like fleece fabrics, etc. Used for surface finishing of various kinds of wood, chemical equipment, telecommunications equipment and instruments, and various transportation tools Used for manufacturing plastic products, wear-resistant synthetic rubber products, synthetic fibers, hard and soft chemical book foamed plastic products, adhesives and coatings, etc. Used for heat insulation and cold insulation of storage tanks, pipes, refrigerators, beer, fermentation tanks, and fresh-keeping barrels, used for heat insulation and waterproof of buildings, and also used for prefabricated polyurethane plates Used for aviation, railway, construction, sports, etc; Used for surface finishing of wooden furniture and metal; Used for thermal insulation and cooling of storage tanks, pipelines, cold storage facilities, beer, fermentation tanks, and fresh-keeping buckets, as well as for building insulation and waterproofing. It can also be used for prefabricated polyurethane boards; It can be used to manufacture plastic products, wear-resistant synthetic rubber products, synthetic fibers, rigid and soft foamed plastic products, adhesives and coatings, etc; Surface coating categories for various types of wood, chemical equipment, telecommunications equipment and instruments, as well as various transportation vehicles. Flammable liquids, hazardous characteristics, solvents, flammable storage and transportation characteristics. Warehouse ventilation, low temperature and drying; Store and transport extinguishing agent dry powder, carbon dioxide, sand, insoluble foam separately from oxidant
