The Advantages VULCAN 161 & Pellet and Granular Size

Polymer pellets or crumbs are added to the hot oil and dispersed by the agitator.

The product is drawn from the base of the vessel into the workhead of the In-Line Mixer.

The polymer is subjected to intense high shear which reduces particle size, exposing an increasing Surface area of polymer to the surrounding base oil, accelerating the solubilization process.

The self-pumping In-Line mixer returns the product to the vessel as fresh material is drawn into the Workhead, continuing the mixing cycle.

Solubilization is completed in a fraction of the time taken by agitation alone.

The rotor/stator workhead rapidly disintegrates the polymer pieces, exposing an increasing surface area of polymer to the base oil.

The high shear action of the In-Line mixer dramatically reduces processing time.

Agglomerated particles are instantly disintegrated in the In-Line mixer’s workhead.

The In-Line mixer concentrates its effort on a relatively small volume within the workhead rather than The entire batch, a more energy efficient process.

Bypassing the intense high shear action of the rotor/stator assembly is impossible, once the product is ─░n the recirculating line.

No additional pumping is required to circulate the product back into the tank. In-Line high shear mixer Can easily be added to an existing vessel and agitator in a recirculation system.vii polymers

Thickeners and viscosity index improvers are polymeric, and are added to lubricants to reduce the Degree of change in viscosity seen at high and low temperatures.

Mineral oil lubricants become less effective at high temperatures because heat reduces their viscosity and film-forming ability.

The traditional solution to this problem was to make seasonal oil changes in some applications. 

With the advent of viscosity improvers, that’s no longer necessary or desirable.

When viscosity improvers are added to low viscosity oils, they effectively thicken the oil as Temperature ─░ncreases.

This means that the lubricating effect of mineral oils can be extended across a wider temperature Range.

When creating a viscosity improver, a balance between the thickening efficiency and shear stability of The polymer is important. Higher molecular weight polymers make better thickeners, but tend to have less Resistance to mechanical shear.

Lower molecular weight polymers are more shear resistant, but do not improve viscosity as effectively At higher temperatures and have to be used in larger quantities.

Polymer additives can also undergo thermal and oxidative degradation, unzipping back to smaller Monomers, which reduces their effect.

The highest possible degree of thermal and oxidative stability is desirable in addition to the features above.


Viscosity improvers is primarily used in multigrade engine oils, gear oils, automatic transmission fluids, Power steering fluids, greases, and some hydraulic fluids.
