AM-146

Styrenated diphenylamine

Styrenated substitution gives a high nitrogen content in a liquid form. Widely used as a cost-efficient aminic in industrial oils and as a stabiliser outside the lubricant market entirely.

Cross-reference

Grades a formulator would benchmark AM-146 against. Naming them is not a claim of equivalence — it is where to start the comparison.

The chemistry

Aminic Antioxidants

High-temperature radical scavenger

Typical treat rate0.3 – 2.0 %

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.
