Trends in the Industry Summary

In various fields one of the major trends is towards Energy Efficiency

The contribution must come from hardware and equipment as well from the fluids need for operation

Lubricants need to further lower the consumption of fuel and energy in all sectors : industrial and automotive and MWF´s

Some minor trends also towards greener solutions but performance requirements are top of the list


How can Lubricants contribute ?

Energy and Fuel Efficiency through the use of Lubricants is mostly contributed through the reduction of friction between contact surfaces and within the lubricant

This can be reached with various approaches Advanced formulation technology

Usage of high performance additives

Choice of superior base stock chemistry


Lubrication

Ester

PAO Gp III

Gp II

Gp I

PAG very good

poor

Lubrication Effects Comparison of Base Stocks


Lube Esters

Polyol Esters

Mono Esters

Di Esters

Complex Esters

Esters for lubricants Categories


Basic ester design rules

branched • Low VI, low pourpoint

linear • High VI, high pourpoint

saturated • High oxidation stability, high pourpoint

unsaturated • Poor oxidation stability, low pourpoint


Test Matrix Test Methods 3 different test methods and instruments have been used

looking at Frictional Behavior/Wear/Film Thickness


Powertrib MTM – test


Test Matrix Ester Base Stocks 10 esters have been evaluated in the project grouped by

VG class and chemistry CHEM 1 : Oleates

CHEM 2 : Branched

CHEM 3 : Saturated


Test Results Shear Stability


Test Results Film Thickness


Test Results Frictional Behavior


Summary

Different Chemistries show different behavior and film thickness

All ester base stocks show comparable shear stability Branched and Oleate systems show highest film thickness

especially at low speed conditions Traction and frictional behavior is even more depending on

chemistry Branched systems show higher friction at same VG class

Oleates have lowest friction values
