Germany’s specialty chemicals company LANXESS has commissioned a new production line at its Mannheim site for the synthesis of dimercaptothiadiazole (DMTD) derivatives. These chemicals are added to lubricants as multifunctional additives. The production line, which started in May 2018, doubles the annual production capacity of these specialty additives. The investment volume is in the single-digit-million-euro range.
“With this investment, we have responded to the increased customer demand for these specialties. The new plant will enable us to meet their requirements for high-quality lubricant additives, but also helps us acquire new customers, and further develop our own package solutions for a rapidly growing market,” says Martin Säwe, head of the Lubricant Additives business line in LANXESS’s Additives (ADD) business unit.
DMTD derivatives are multifunctional additives and are initially used as corrosion protection for lubricants in contact with steel alloys containing so-called nonferrous metals such as copper, nickel or cobalt. They prevent the leaching of nonferrous metal ions from the alloy, protect the metal surface from aggressive chemicals, and thus guarantee the integrity and longevity of steel alloys. Because of their metal-surface bond, they also act as lubricants, even when under extreme conditions and high pressures metal surfaces start contacting each other. Therefore, and in addition to their function – that is, to provide protection against corrosion, they are also referred to as extreme pressure additives. Last but not least, these additives interact with and absorb aggressive chemical breakdown products in the lubricant, which could otherwise cause material damage in the long term. The main areas of application for these products are industrial oils, greases, and metalworking fluids.
Under the Additin brand name, LANXESS supplies customers worldwide with DMTD derivatives, which are also used in additive packages. The products are manufactured exclusively at the site in Mannheim.
