Eastman Chemical Company, based in Kingsport, Tennessee, U.S.A., plans to increase its Therminol^® 66 heat transfer fluid manufacturing capacity in Anniston,  Alabama, U.S.A. The plant expansion is expected to be complete in 2024 and will increase U.S.-based capacity by 50%. 

Eastman offers a family of Therminol heat-stable fluids developed specifically for indirect transfer of process heat. The Therminol brand is the top-selling synthetic heat transfer fluid in the world, with manufacturing facilities on four continents. Therminol 66 is the world’s most popular high temperature, liquid-phase heat transfer fluid.

“We are significantly investing in the expansion of our worldwide capacities to ensure  we meet the needs of our customers around the world for years to come,” said Sharon  Dunn, Eastman’s general manager for specialty fluids and energy. “The planned  capacity increase in the U.S. demonstrates our deep commitment and further solidifies  our leading position in the heat transfer fluid market.”  

In addition to its Therminol site in Anniston, Eastman manufactures the product in  Newport, Wales, U.K.. Eastman also manufactures other Therminol products in  Suzhou, China, under a joint venture. 

In 2019, Eastman acquired from Sasol, a global chemical and energy company, the Marlotherm heat transfer fluids manufacturing assets located in Germany and related formulations, intellectual property and customer contracts. This acquisition enabled Eastman to expand its heat transfer fluids product offerings to customers around the globe.
