Comparison of performance and characteristic of suberate, azelate and sebacate as PVC plasticizers

Consumer’s health and safety problems that arise from using di (2-ethylhexyl) phthalate (DEHP) as a conventional plasticizer for PVC have led to the study of the production of alternative plasticizers based on dicarboxylate esters. In this study diester plasticizers based on suberic, azelaic and seb...
