Synton® High Viscosity PAO Base Fluids 

Synton® PAO products are high viscosity, highly saturated, linear/ branched polymers that are designed to be used as the high viscosity synthetic oil or viscosity modifier component of a high performance lubricant or synthetic lubricant formulation.

The highly saturated chemistry provides excellent response to antioxidants and can be an asset in a lubricant formulation for use under high temperature conditions. Blends made with Synton® PAO products can have a high Viscosity Index, with good low and high temperature performance, providing a lubricant that is usable under widely varying temperature conditions. 

The relatively low molecular weight of the Synton® PAO products, compared to the classic viscosity modifiers, makes these products stable to the significant shear stresses seen in many applications – especially gear oils. This shear stability behavior, both temporary and permanent, means a more consistent oil film thickness is provided to the working parts and can potentially help with wear protection.
