Both DOP (dioctyl phthalate) and DOTP (dioctyl terephthalate) primarily function to impart flexibility, toughness, and ease of processing to rigid plastics (especially polyvinyl chloride, PVC), but their key differences determine their different application focuses. DOP, as a general-purpose plasticizer, mainly serves to efficiently and economically lower the glass transition temperature of plastics, making them soft and pliable at room temperature. It is widely used in cost-sensitive traditiona
