Description
1. Product Overview
The Anti-Oxidant Additive — Oil stability is a high-performance synthetic formulation engineered to inhibit oxidative degradation in industrial lubricants, transformer oils, and bio-based fluids. Its primary industrial use is extending oil service life under high-temperature and high-shear conditions, reducing sludge formation and viscosity increase. The key value proposition is a measurable 40–60% reduction in total oxidation products compared to conventional phenolic antioxidants, delivering lower total cost of ownership for asset-intensive operations. Strategically, with global regulations tightening on hazardous degradation byproducts and maintenance downtime costs rising, this additive is critical for operators seeking compliance, uptime, and sustainability without re-engineering their fluid systems.

3. Core Industrial Applications
| Primary Industry | Operational Use Case | Performance Advantage |
|---|---|---|
| Power generation & T&D | Transformer oil stabilization (mineral & natural ester) | 2× longer oxidation induction time (RPVOT) vs. BHT; lower dielectric loss factor |
| Heavy machinery & mining | Circulating oils, gear oils, hydraulic fluids operating >80°C | Reduces varnish deposits by 70%, extending drain intervals by 3,000+ hours |
| Marine & shipping | Medium-speed trunk piston engine oils, stern tube lubricants | Compatible with high-alkaline detergents; no filter plugging or emulsion issues |
| Bio-lubricant manufacturing | Vegetable-based hydraulic fluids (HEES, HETG) | Prevents rancidity and acidic byproducts; passes EN 14522 stability test at lower dosage (0.3–0.5% wt.) |
Efficiency advantage: Requires 20–30% lower treat rate than competing phenolic antioxidants to achieve the same Rancimat induction time (110°C, air flow 10 L/h).
