Description of DAE
DAE Aromatic Rubber oil (distillate aromatic extract, abbreviated as DAE) distillate aromatic extracts have very high aromatic contents. Distillate aromatic extracts are obtained as a by-product of the process of solvent extraction of vacuum distillates used as a raw material in the manufacture of p m lubricant base oils. DAE grades are DAE 10, DAE 11, DAE 20, DAE 40, DAE 50, DAE 60 . Aromatic extracts refer to solvent extracts of distillates or the residue (residuum) from a vacuum tower; these substances are complex, highly viscous liquids that contain predominately aromatic hydrocarbons covering the carbon number range of C15 to C50. Aromatic extracts are produced during the refining of lubricating oil basestocks and waxes. Distillate Aromatic Extract (DAE) consists predominantly of aromatic hydrocarbons having carbon numbers in the range approximately C15 to C50. Distillate Aromatic Extracts have very high aromatic contents. Distillate aromatic extracts are obtained as a byproduct…
