BLS® 1710 is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. BLS® 1710 protects polymers as well as organic pigments from UV radiation helping to preserve the original appearance and physical integrity of engineered plastics, elastomers, PVC, adhesives, and polyurethanes during outdoor weathering.

Applications: BLS® 1710 features a strong absorption of ultraviolet radiation in the 300-400 nm region. It has a high degree of photostability as its characteristics and structure is unchanged over long periods of light exposure. BLS® 1710 provides ultraviolet protection in a wide variety of polymers including styrene homo- and copolymers, engineering plastics such as polyesters and acrylic resins, polyvinyl chloride, and other halogen containing polymers and copolymers, acetals and some cellulose esters. Elastomers, adhesives, polycarbonate blends, polyurethanes and epoxy materials also benefit from use of BLS® 1710. BLS® 1710 performs synergistically when used in combination with other hindered amine light stabilizers like BLS® 1944.
