Polyurethane is the transformer of polymer materials

Polyurethane (PU) material //www.mingxupu.com/en/products-pu.html  is a kind of organic polymer material gradually emerging in recent years. It is prepared by reaction of dimer or trimer of isocyanate with polyols, and it is a kind of macromolecular compounds containing repeated polyurethane structural units in the molecular main chain. According to different formulations and preparation methods, different polyurethane materials can be prepared, including rigid foam//www.mingxupu.com/en/products-pu.html, flexible foam, semi-rigid foam, elastic fiber, adhesive, coating, spandex and so on. Polyurethane compounds usually have the characteristics of wear resistance, foamability, solvent resistance, low temperature resistance, adhesion, biological aging resistance and so on. It can be widely used in construction, aviation, medical and health, home appliances, transportation, new energy, environmental protection and many other fields. It is also a kind of organic polymer material with the largest variety and the most widely used among polymer materials.
