Products
Durasyn® polyalpha olefins are manufactured by INEOS Oligomers using integrated feedstock. The physical and chemical properties of PAOs are ideal to meet the demanding requirements of formulations for high quality synthetic lubricants.
Production process and chemical structure
Durasyn fluids are polyalpha olefins manufactured through a multistage process that begins with ethylene as the building block. 1-Decene is one of the alpha olefin monomers used in the production of Durasyn polyalpha olefins and it is oligomerized in the presence of an acidic catalyst to give a mixture of decene dimers, trimers, tetramers and higher oligomers. In the next step, this mixture of oligomers is distilled to permit the tailoring of the oligomer distribution and produce specific product cuts designated by their Kinematic Viscosities at 100°C.
In the final step, these highly branched decene oligomers are additionally hydrogenated and filtered to produce the Durasyn grades. Hydrogenation is necessary to give the final product enhanced chemical inertness and added oxidative stability. A wide range of viscosities can be produced, the most common viscosity grades being 2,4,6,8, and 10cSt at 100º C. The final process gives a limited and clearly defined set of very stable molecules with a paraffinic structure.
