Pine trees from sustainable managed forests form the basis of much of today’s pulp and paper production. During the Kraft paper production one of the pine chemicals is extracted as Crude Tall Oil (derived from the Swedish word “tallolja” or pine oil). Tall Oil Fatty Acid, Tofa, is made out of this Crude Tall Oil. The Valilube and Valiflex ester products are Tofa or dimer based. Umicore has developed a range of esters used in lubricant applications with very good to exceptional low and high temperature properties and very low volatility for high performance. Some esters are designed to replace conventional vegetable oil based lubricants, offering improved thermal, oxidative and storage stability.
Umicore is also a producer of Bi and Zn Naphthenates used as protective additives in grease production.
