UV absorbers are used to solve the problem of yellowing of PU (Polyurethane). Nowadays, the requirements for the durability and weather resistance of polymer materials are becoming more and more stringent. Adding UV absorbers can improve product cracking, powdering, yellowing, and decrease in tensile strength, problems such as changes in elongation. Choosing the appropriate UV absorber can make the product achieve better light and weather resistance.
