👉 The Dans fluid, also known as Dans oil, is a synthetic lubricant developed by the French company Danser in 1959. It's designed to mimic the properties of natural lubricants found in animal fats and oils, particularly those used by marine mammals like seals. The fluid is a complex mixture of fatty acids and esters, engineered to provide excellent viscosity stability, low toxicity, and superior performance in extreme conditions, such as high temperatures and pressures. Its unique composition allows it to maintain lubrication even under harsh environments, making it invaluable for applications like marine engines, industrial machinery, and aerospace components where traditional lubricants might fail.
