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.
The aromatic extracts can be grouped into two subcategories, distillate aromatic extracts (DAEs) and residual aromatic extracts (RAEs), according to the class of lubricating oil feedstock from which they are derived. The aromatic extracts are used as blending components of heavy fuels, as feed stock for production of carbon black, petroleum pitches and resins, and in the manufacture of rubber and plastics.
To meet the HPV Challenge, the Testing Group has thoroughly evaluated the substances within the Aromatic Extracts category and has made all of the reliable human health and ecological hazard data available to the public. The environmental fate of aromatic extracts is determined by the individual hydrocarbons present within the mixture.
Because of their physical and chemical properties, these substances will tend to agglomerate rather than disperse if released to the environment. Some aromatic extracts have been found to cause toxicity in freshwater invertebrates and algae. The human health effects of aromatic extracts vary between acute and repeated-dose studies and between DAEs and RAEs.
What are the DAE’s:
There are 3 substances included in the distillate aromatic extracts (DAEs) assessment. These 3 substances are a subset of aromatic extract substances and are complex combinations of hydrocarbons. These aromatic extracts are produced as by-products during the refining of crude oil.
These DAEs can be blended to make other petroleum substances.
Due to their untreated nature, these substances have high levels of aromatic compounds, including polycyclic aromatic hydrocarbons (PAHs).
Uses of DAE:
DAE distillated aromatic extract combination is used as:
- Carrier oils
- Plasticizer
- Diluents & filling agent
- Good Solubility Properties
- processing ability of rubber in milling and mixing
- Heavy fuels
- Feed stock for production of carbon black
- Petroleum pitches and resins
- Manufacture of rubber and plastics
