Base Oils Data

Based on a variety of chemistries and can be used for both Tinplate and Sheet rolling.

The esters are manufactured to give controlled and consistent lubrication performanceand to give excellent post-anneal cleanliness.

* Inflection Point is the temperature where the rate of weight loss is at its maximum

** Midpoint is the temperature where the weight loss of the product is 50%



Lubricity Booster Data

Dimer acids and complex esters providing excellent lubricity boosting properties. Complex esters also have the advantage of being cleaner post-anneal.

Broad range of emulsifiers to optimise particle size and stability

Two or more emulsifiers are used in combination to get the perfect balance

between emulsion spontaneity and stability

Particle size distribution using Hypermer A70Particle size distribution using Hypermer B261

Unique polymeric emulsifiers that control the particle size and therefore

controls the amount of oil that plates-out on the surface of the strip and theamount of lubrication.

They are shear stable and resist the formation of multi-modal particledistributions which lead to irregular lubrication in the roll bite.

These graphs demonstrate that the Hypermer completely rejects the tramp oil.

The unique chemistry of the Hypermers prevents any emulsification of thetramp oil.
