ABSTRACT:Polyurethane products are numerous and widely used in fields, such as foams, elastomers, elastic fibers, coatings, and adhesives, etc. Polyurethane catalyst is an important part of polyurethane. In the production of polyurethane, the catalyst plays an important role. According to the different uses of polyurethane, different catalysts are needed to give polyurethane special properties. Therefore, polyurethane has many types of catalys. But, it is used to polyurethane foaming and curing is mainly amine catalysts. Amine catalysts and their main technologies are mainly introduced in this paper.
