Description and Uses

Dioctyl terephthalate, also known as DOTP, is used as a plasticizer in the production of PVC and other copolymers. It is the ester of terephthalic acid and 2-ethylhexanol. It is a clear, colourless liquid with a slight odour, which is insoluble in water. DOTP can be used as a direct replacement for DOP and DINP in a range of applications due to its thermal resistance, excellent durability and transparency. It is used in a variety of processes such as calendering, extrusion and injection molding.

DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films. It may also be used as a plasticizer with polyvinyl chloride (PVC) to form solutions for artificial intravessel plaque.
