Di-octyl Phthalate (DOP): Chemical Name:Also known as dioctyl phthalate or DEHP (di(2-ethylhexyl) phthalate). Structure: A phthalate ester made from phthalic acid and 2-ethylhexanol. Uses:Widely used as a plasticizer in PVC (polyvinyl chloride) to increase flexibility and durability—think vinyl flooring, cables, and medical devices. Properties: Colorless, oily liquid with low volatility. Concerns:It’s been flagged for potential health risks (e.g., endocrine disruption), leading to restrictions i

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 brittleness without altering th
