Lubricating grease can be defined as a solid-to-semifluid product of a thickening agent in a liquid lubricant. Therefore, grease consists of three fundamental components: a lubricating base fluid, a thickener and additives. The oil, thickener, and additive combinations provide manufacturers with a great deal of flexibility in formulating products with many different physical and chemical attributes.

The choice of the base and co-base oils, representing 80% to 90% of the total formula, has a big impact on the grease performance. Although the market is dominated by Lithium and Lithium complex thickeners with conventional mineral oil base fluids, esters are necessary when a broader operating temperature range must be met and/or when biodegradability is required.

The lower Group I base stock availability forces to find higher viscosity grades alternatives. IQLubricants offers a wide range of high viscosity esters in order to meet the required viscosity grade. Moreover, IQLubricants offers a wide range of organic esters Docadit FL series, which can be used to formulate H1 greases for food grade applications.
