- Product Highlights
Aromatic esters are a unique class of synthetic esters which are made from an aromatic polycarboxylic acid such as trimellitic or pyromellitic acid and a monofunctional alcohol. The aromatic center is a strong and stable core structure, providing excellent thermal, oxidative and hydrolytic stability. The multiple ester groups create polarity that enhance the fluids ability to solubilize degradation products. Aromatic esters are high viscosity base oils that are extremely stable to thermal and chemical attack.
Aromatic esters have a narrow molecular weight distribution, and do not contain volatile light fractions or heavy fractions which can lead to weight loss or polymerization in service. While favored for their stability, the rigid aromatic group reduces lubricity and viscosity index compared to high viscosity complex esters. Aromatic esters exhibit a low pour point, but their use in extreme cold environments is limited because their viscosity increases rapidly at low temperatures.
Aromatic esters are preferred base fluids for high temperature applications. They have low volatility and will not form polymer varnish which helps extend fluid and equipment life. This feature makes them well suited for use in compressor fluids, gear oils, oven chain lubricants and grease.
