Applications UV Absorber P is an effective light stabilizer for variety of polymers including styrene homo-and copolymers, engineering plastics such as polyesters and acrylicresins, polyvinyl chloride, and other halogen containing polymers and copolymers(e.g. vinylidenes), acetals, elastomer and cellulose esters.

Elastomers, adhesives, polycarbonate blends, polyurethanes, and some cellulose

esters and epoxy materials also benefit from the use of UV Absorber P

UV-P used in polyurethane UV-P used in ABS/polycarbonate blend

UV-P used in elastomer UV-P used ABS material

Features / Benefits: UV Absorber P features a strong absorption of ultraviolet radiation in the300-400 nm region. It also has a high degree of photostability over long periodsof light exposure.
