Light Stabilizer for PVC

Traditionally, polyvinyl chloride (PVC) anti-light aging is mainly used for benzophenone-based light-stabilizing systems. It is generally believed that hindered amine light stabilizers with better application effects in polyolefins are not suitable for PVC systems. The light stabilizer was tested on PVC film, and the results showed that the light stabilizer was used in PVC, and its light and heat stabilizing effect was similar to that of benzophenone ultraviolet light stabilizers. It is an acrylic polymer with dustproof function for PVC. The surface coating is beneficial to the UV stability of PVC.
