TRANSCRIPT
Synthetic high performance basestocks
Hydrogenated (saturated) olefin polymers
Manufactured by the catalytic oligomerization of linear alphaolefins
Wax-free combination of molecules of predetermined chain length

PAO Manufacturing Process
Conventional PAO- prominent “backbone” and relatively
uniform structure provides superior lubricating performance versus mineral oils
SpectraSyn Ultra™ High VI PAO- very uniform, comb-like structure- absence of short side chains results in
rheological advantages providing unique lubricant benefits

Thermal Stability
The low traction of SpectraSyn™ PAOs may increase allowable gear loading / reduce
scuffing & improve gear durability
Scuffing Hypothesis:Scuffing occurs when Frictional Power Intensity (FPI) exceeds critical limit.
FPI = (Traction)*(Power)*(V2 - V1)2*A*λ
