About Phthalic Anhydride

This colourless solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics.Phthalate plasticizers are used for the production of flexible PVC products such as cables, pipes and hoses, leather cloth, shoes, film for packaging etc.Phthalic anhydride has another major use in the production of polyester resins and other minor uses in the production of alkyd resins
