polyoliestereistä

Polyoliesterit are synthetic ester compounds derived from polyols and carboxylic acids. They are characterized by the presence of multiple ester linkages within their molecular structure. The specific properties of a polyoliester are determined by the choice of the polyol and the carboxylic acid used in its synthesis. Common polyols include neopentyl glycol, trimethylolpropane, and pentaerythritol, while fatty acids such as oleic acid and stearic acid are frequently employed.

Polyoliesterit find widespread application as lubricants due to their excellent thermal stability, oxidative resistance, and low volatility. These properties make them suitable for demanding environments, including jet engine oils, automotive lubricants, and industrial hydraulic fluids. They also exhibit good biodegradability and low toxicity compared to some mineral oil-based lubricants.

Beyond lubrication, polyoliesterit are utilized as plasticizers in polymers, improving their flexibility and processability. They can also be found in formulations for coatings, adhesives, and surfactants. The versatility of polyoliester chemistry allows for tailoring their properties to meet specific performance requirements across various industries.
