Products Description of Dioctyl Terephthalate CAS#6422-86-2
Dioctyl terephthalate (DOTP) is a plasticizer commonly used in the production of PVC and other copolymers. It is the ester of terephthalic acid and 2-ethylhexanol. DOTP is a clear, colorless liquid with a slight odor and is insoluble in water. Thanks to its thermal resistance, excellent durability, and transparency, DOTP can serve as a direct replacement for DOP and DINP in various applications. It is suitable for use in multiple processing methods, including calendering, extrusion, and injection molding.
