👉 The ac fluid, also known as acetone-formaldehyde copolymer fluid, is a specialized lubricant used in high-performance engines, particularly in aircraft and high-power machinery. It's a blend of acetone and formaldehyde, with the fluid properties finely tuned to reduce friction, wear, and heat generation. This fluid acts as a protective layer between moving parts, enhancing engine efficiency and longevity by minimizing metal-to-metal contact. Its low viscosity allows for easy circulation, ensuring optimal lubrication even under extreme operating conditions. The copolymer nature of the fluid also contributes to its stability and resistance to degradation, making it an indispensable component in demanding environments where conventional lubricants would fail.
