Problem Analysis and Suggestions on Environmental Plasticizers
Current plasticizers,such as dioctyl phthalate(DOP)and dioctyl terephthalate(DOTP)used to improve the properties of polyvinyl chloride(PVC)plastic products were introduced.The application status and existing problems of traditional plasticizers such as DOP were analyzed.Environment-friendly plasticizers such as citric acid esters,para phenyls,epoxides,and polyester plasticizers were analyzed and elaborated from basic situation,production process,physical and chemical properties.Problems and suggestions were also proposed for the application status of different types of plasticizers to provide a reference for the further development and application of environment friendly plasticizers.
