Problems solved by technology

With the advancement of science and technology, people have put forward higher requirements for the performance of polyurethane. The research on the modification of polyurethane has become a research hotspot in recent years, but ordinary polyurethane materials are easy to hydrolyze, and there are water resistance and surface properties in the process of use. Poor, easy to be destroyed by bacteria, which greatly limits the practical application of polyurethane materials
