Viscosity Improvers
Viscosity improvers are additives used in aviation lubricants to enhance the viscosity-temperature relationship of the base oil. They are long-chain polymers that help to maintain the lubricant's viscosity at high temperatures and improve its fluidity at low temperatures. Viscosity improvers are essential for aviation lubricants as they ensure that the lubricant maintains its protective properties in a wide range of operating temperatures. Without viscosity improvers, the lubricant's viscosity would decrease at high temperatures, leading to metal-to-metal contact and wear, while at low temperatures, the lubricant would become too thick to flow, leading to poor engine performance.
