Applications

RIASORB® UV-P provides ultraviolet protection in a wide variety of polymers including styrene homo- and copolymers, engineering plastics such as polyesters and acrylic resins, PVC, and other halogen containing polymers and copolymers (e.g. vinylidenes), acetals and cellulose esters. Elastomers, adhesives, polycarbonate blends, polyurethanes, and some cellulose esters and epoxy materials also benefit from the use of RIASORB® UV-P. RIASORB® UV-P features a strong absorption of ultraviolet radiation in the 300-400 nm regions. It also has a high degree of photo stability over long periods of light exposure. The high absorbance combined with photo stability and the ability to release absorbed energy in non-sensitizing ways make RIASORB® UV-P an effective stabilizer against the effects of ultraviolet light. The recommended dosage of RIASORB® UV-P is 0.10-0.50%, the exact addition should be determined in trails.
