A range of viscosity index improvers are available for use in multigrade engine oils and aftermarket applications. The viscosity modifiers offer cost effective thickening efficiency. The viscosity modifiers are available in a range of SSI grades in pellet, bale, or liquid forms.
VI Improvers are used to alter the degree of viscosity of the lubricant through a wide range of temperatures but generally tend to be added to low temperature/low viscosity oils.
These additives alter the rheological properties of the lubricant when subjected to fluctuating temperatures in the field. They provide other benefits such as durability, protection from wear and tear on equipment, efficiency improvement, cleanliness and finally low temperature performance.
