Polyalphaolefin Synthetic Basestocks

Group IV BasestocksPolyalphaolefins

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

What are Poly Alpha Olefins (PAO)?

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
