The Trend of Additives for Poly(vinyl chloride) as Photostabilizers: Review Article

Abstract

Conservation of poly(vinyl chloride) from the ultraviolet light that causes degradation, have very attention in recent decades. PVC formularizations have a large number of additives playing fundamental functions during their conversion and adjusting the behavior properties of final products. In this review, various types of additives are briefly discussed to show their important properties and reasons for addition to their essential mechanisms that cause retardation of photo-degradation. The additives including organotin(IV), UV screeners, organic UV absorber and free-radical scavengers.
