Anti-hydrolysis Additives for Polyester Polyurethanes: Enhancing Durability and Performance

introduction polyester polyurethanes (pups) are widely used in a variety of applications, including coatings, adhesives, elastomers, and foams, due to their excellent mechanical properties, abrasion resistance, and chemical resistance. however, a significant drawback of polyester-based polyurethanes is their susceptibility to hydrolytic degradation. this is because the ester linkages within the polyester polyol backbone are vulnerable to cleavage in the presence of water, especially under acidic or…
