Dioctyl terephthalate is an almost colorless liquid with low viscosity, offering a smooth and seamless flow. Its viscosity sits at 63 mPa.s at 25ºC, reducing to 5 mPa.s when warmed to 100ºC, and significantly increasing to 410 mPa.s when chilled to 0ºC. The freezing point is a chilly -48ºC, while the boiling point reaches an impressive 383ºCat (0.1) MPa.s at 0ºC. Its ignition point is 399ºC, with a refractive index of 1.4887 and minimal water-solubility of 0.4% at 20ºC.
