Technical Abstract: This article provides a general overview of estolide technology and compares the four major types of estolides: synthetic estolides from unsaturated fatty acids, natural estolides from hydroxy oils, synthetic estolides from hydroxy oils, and synthetic estolides from hydroxy fatty acids. The synthetic estolides from unsaturated fatty acids are currently being commercialized and offer a wide range of physical properties to meet various lubricant applications. All the estolides classes offer good lubricity and cold temperature properties equivalent or better than commercial petroleum or vegetable based lubricants.
