Plasticizer Leon on Instagram: "The Role of DOP Plasticizer in Polymers Dioctyl phthalate (DOP), also known as di(2-ethylhexyl) phthalate (DEHP), is a high-production-volume phthalate ester widely used as a general-purpose plasticizer, primarily in polyvinyl chloride (PVC). Its core function is to impart flexibility, elasticity, and workability to rigid polymers by intercalating between polymer chains, reducing intermolecular forces, lowering the glass transition temperature (Tg), and decreasing
