Zeller+Gmelin introduces alternative to lithium grease
Many companies use lithium hydroxide as a raw material to thicken their greases. Lithium greases are suitable for a wide range of temperature and load conditions and can therefore be used in many technical applications. With nearly a 70% market share, lithium soap has been used widely as a grease thickener for decades.
However, due to the increased demand for lithium-ion batteries, lithium is also becoming attractive for other industries such as the electrical or automotive sectors. The e-mobility trend is creating a real hype for lithium hydroxide, so sharp price increases and depleted supply chains are anticipated.
“Of course, this market change has not gone unnoticed by us,” said Christian Stapper, product manager, Lubricating Greases, Zeller+Gmelin, a lubricant manufacturer based in Esslingen, Germany. “As a sustainability-oriented company, we see now as the right time to offer lithium-free greases to the market.”
Zeller+Gmelin has launched a lithium-free grease developed entirely with calcium soap. Divinol Multipurpose Grease Ca 2 will serve as a high-performance alternative to the proven Divinol Multipurpose Grease 2. This multipurpose grease offers a temperature application range of -30 to +120 °C and is designed to lubricate roller and plain bearings subjected to normal thermal and mechanical loads in machines of all kinds, blowers, pumps, presses, calendars etc.
“Our laboratory team is constantly researching alternative thickening technologies and is currently optimising the use of calcium soap,” Stapper said. “Based on this lithium-free thickener, we are developing new, high-quality lubricating greases that are suitable for demanding rolling bearing applications, among others.”
Calcium soap grease offers reliable wear and corrosion protection and is also resistant to water and oxidation, the company said.
