Hydrogenated terphenyls

Hydrogenated terphenyls (CAS 61788-32-7) are synthetic aromatic hydrocarbons produced by catalytic hydrogenation of terphenyl isomers; a thermally stable fluid used as a high-temperature lubricant and process fluid.

Where is Hydrogenated terphenyls used?

• High-temperature lubrication: base fluids or blending components
• Heat transfer fluids, compressor oils and specialty greases operating above mineral oil limits
• Refineries and petrochemical plants use them in process fluid systems with sustained elevated-temperature exposure.
• Carrier fluids and solvents in industrial formulations needing thermal and oxidative stability
• Metalworking and specialty machining: incorporated into cutting and forming fluids for high-load, high-temperature contact

Commercial specifications

• Viscosity grade, flash point and aromatic content define specifications
