Polyurethane additives are chemical compounds added to polyurethane (PU) formulations to optimize their characteristics, performance, and processing. Polyurethanes are versatile, high-performance polymers used in a wide range of applications, such as foams, coatings, adhesives, sealants, elastomers, and fibers. By incorporating specific additives, manufacturers can tailor polyurethane properties to better suit their intended use.
