Hydrogenated terphenyls

Hydrogenated terphenyls (CAS 61788-32-7 ) are a class of synthetic aromatic hydrocarbons produced by the catalytic hydrogenation of terphenyl isomers, yielding a thermally stable fluid used as a high-temperature lubricant and process fluid. Their combination of thermal stability and low volatility makes them a preferred base fluid in demanding industrial environments where conventional mineral oils fall short. In high-temperature lubrication, they function as base fluids or blending components. These fluids are utilized in heat transfer fluids, compressor oils, and specialty greases operating above the practical limits of mineral oil. Refineries and petrochemical plants use them in process fluid systems where sustained exposure to elevated temperatures occurs. They also serve as carrier fluids and solvents in industrial formulations where thermal and oxidative stability are critical to product performance. In metalworking and specialty machining operations, they are incorporated into cutting and forming fluids. These formulations are designed for high-load, high-temperature contact conditions. Hydrogenated terphenyls are supplied as a clear to pale yellow viscous liquid. Technical-grade material is the standard commercial offering for industrial use. Specifications are typically defined by viscosity grade, flash point, and aromatic content to suit specific lubrication or process fluid requirements. This ensures consistent performance across various demanding chemical and mechanical applications. Contact us for supply of Hydrogenated terphenyls Request Quote
