Product Properties
1.UV-P provides ultraviolet protection in a wide variety of polymers including styrene homo- and copolymers, engineeringplastics such as polyesters and acrylic resins, PVc, and other halogen containing polymers and copolymers (e.g. vinylidenes)acetals and cellulose esters.
2.Elastomers, adhesives, polycarbonate blends, polyurethanes, and some cellulose esters andepoxy materials also benefit from the use of UV-P.
3.UV-P features a strong absorption of ultraviolet radiation in the 300-400nm regions.
4.it also has a high degree of photo stability over long periods of light exposure. The high absorbance combinedwith photo stability and the ability to release absorbed energy in non-sensitizing ways make UV-P an effective stabilizeragainst the effects of ultraviolet light.
