Elevance Renewable Sciences, Inc. has expanded commercial availability of Elevance Aria WTP 40. The company said the high-viscosity lubricant base stock that combines the composition and properties of two key synthetic base stock technologies into a single, high-performance product designed to provide differentiated performance in broad markets such as engine and gear lubricants, industrial and hydraulic fluids, and greases is now available to customers globally.

“The customer response to the initial data we introduced at the 9th Pan American ICIS Base Oils and Lubricants conference last December has been strong and positive,” said Robin Weitkamp, senior vice president, Lubricants and Additives for Elevance. “We are pleased that we’re now able to bring this product to the market globally.”

During the London seminar, the company presented data on Elevance Aria™ WTP 40, a renewable, high-performance synthetic base stock. The base stock’s high viscosity index of 160 demonstrates its wide temperature performance and its balanced aniline point of 95 is an improvement over both Group IV and Group V synthetic base stocks. Data presented for the product also indicated Elevance Aria WTP 40 4 ball wear scars in a 75W90 GL-5 fully formulated lubricant formulation were improved more than 50 percent as compared to fully formulated PAO40/ester blends. The company also provided information on the product’s increased deposit control and cleanliness as well as excellent shear stability.

This base stock is made possible due to Elevance’s Inherent renewable building blocks, which enable novel base stock and additive architectures that result in improved performance aimed at addressing today’s challenging lubricant industry requirements.

Inherent renewable building blocks’ versatile chain lengths and di-functional structures enable the synthesis of lubricant components suitable for greases, metalworking fluids, and industrial and transportation lubricants. Inherent products can create new families of base stocks that combine the benefits of two key synthetic base stock technologies — synthetic esters and PAOs — into a single, high-performing molecule that provides advanced lubricating properties and excellent compatibility characteristics.

The company’s 180,000 MT joint venture biorefinery now operating in Gresik, Indonesia, gives Elevance and its partners the materials to develop and commercialize high-performance renewable lubricant components and finished lubricants. For example, Inherent C18 Diacid, a long-chain diacid, is already commercially available as a lubricant component feedstock.
