ASTM DefinitionA synthetic lubricant is a product which consists of stocksmanufatured by chemical synthesis and containing necessaryperformance additivesASTM Classification Synthetic Base Fluids

1. Synthetic Hydrocarbon• Alkylated Aromatics • Olefin Oligomers (PAO) : more widely used• Cycloaliphatics

2. Organic Esters• Dibasic Acid Esters• Polyol Esters

3. Others• Halogenated Hydrocarbons• Phosphate Esters• Polyglycol Ethers• Polyphenyl Ethers• Silicate Esters• Silicones

• Blends• Mixtures of the above
