Dioctyl Terephthalate (DOTP)

DOTP is available in standard industrial grades with high purity, typically above 99%, suitable for demanding processing environments. Chemically, it is a terephthalate ester with the molecular formula C₂₄H₃₈O₄ and a molecular weight of approximately 390.56 g/mol, characterized by low migration, low odor, and strong thermal stability. DOTP is primarily used as a plasticizer for flexible PVC, especially in applications requiring enhanced safety and regulatory compliance. Typical uses include cables and wires, automotive interiors, flooring, wall coverings, synthetic leather, films, sheets, hoses, toys, and medical or consumer products. In addition, DOTP is applied in adhesives, sealants, and coatings where flexibility, aging resistance, and stable mechanical properties are required. It provides excellent electrical insulation, good low-temperature flexibility, and consistent processing behavior, making it suitable for both calendering and extrusion processes.
