Physical and chemical modifications of poly(vinyl chloride) materials to prevent plasticizer migration - Still on the run

Poly (vinyl chloride)(PVC), as the second general plastic just following the product of polyethylene (PE), has been widely applied in building, electrical parts, automobile, package and other fields of our common life. PVC products have accounted for about 80% of all plasticizers consumed. Phthalates, as the mostly used plasticizers, have gradually been restricted because of their migration and reproductive toxicity. This paper is an overview of etnrent understanding in the areas of issues caused by migration of plasticizers from flexible PVC products and the current bans in dealing with these issues. The countermeasures and the recent scientific strategies to prevent plasticizer migration from PVC materials are comprehensibly reviewed. The advantages and disadvantages of various strategies are compared to conduct more in-depth research and find more scientific and effective solutions.
