AM-144
Di-nonylated diphenylamine
The longest alkyl chain in the aminic range, which is what gives it the best solubility and the lowest volatility. Preferred in ester-based and high-VI synthetic fluids.

Grades a formulator would benchmark AM-144 against. Naming them is not a claim of equivalence — it is where to start the comparison.
Aminic Antioxidants
High-temperature radical scavenger
Alkylated diphenylamines and naphthylamines. They terminate the peroxy radical chain at temperatures where hindered phenols have already been consumed, which makes them the backbone of any oil expected to survive above roughly 120 °C. Aminic and phenolic antioxidants are near-always used together — the pair is synergistic, not redundant.
Engine Oils
Passenger-car, heavy-duty and gas engine crankcase formulations, including low-SAPS.
Industrial Gear Oils
Enclosed gear drives, wind turbine gearboxes and heavy industrial reducers.
Greases
Lithium, lithium-complex, calcium sulfonate and polyurea thickened greases.
Turbine & Compressor Oils
Steam, gas and hydro turbine oils, rotary and reciprocating compressor fluids.
Rust Preventives & Quenching
Slushing oils, export packaging fluids, quench oils and heat-treatment fluids.
A full technical data sheet, safety data sheet in the language of the receiving country, REACH status statement and SVHC declaration are issued with every enquiry for AM-144. Certificates of analysis accompany each consignment and retained samples are held for the full shelf life.
