Applications

UV P is an effective polymeric light stabilizer. It can be widely used in engineering plastics and homologous styrene copolymer, such as polyester, acrylic resin and other halogen polymers or copolymers (such as vinylene), acetal, cellulose ester etc.. UV P also applies to elastomers, adhesives, polycarbonate blends, polyurethanes, other cellulose esters, and epoxy materials.
It has also a strong ability to absorb ultraviolet light in the range of 300-400nm. UV P has a superior photostability under long-term sunshine.
