polyesteröljyn

Polyesteröljyn, often referred to as polyester oil, is a synthetic lubricant that is chemically based on polyester. Polyesters are a class of polymers containing ester functional groups in their main chain. These lubricants are engineered for specific applications requiring high performance characteristics.

The properties of polyester oil can vary greatly depending on the specific type of polyester used and the additives incorporated. Generally, they exhibit excellent thermal stability, meaning they can withstand high temperatures without significant degradation. This makes them suitable for use in demanding environments where mineral oils might fail. They also tend to have good oxidative stability, resisting breakdown when exposed to air over time.

Furthermore, polyester oils are known for their good lubricity, providing a protective film between moving parts to reduce friction and wear. Their viscosity can be precisely controlled during manufacturing, allowing for tailor-made lubricants for various viscosities. They also often display good compatibility with seals and other materials commonly found in machinery. Due to their synthetic nature, they can be formulated to be biodegradable in certain instances, offering an environmentally friendlier alternative to some traditional lubricants. Polyester oils find applications in areas such as compressors, turbines, and high-temperature industrial equipment.
