Product Advantages
Highly Efficient at Low Dosage
Requires minimal usage (typically 0.01%–0.1%) while delivering superior antioxidant performance compared to conventional amines.
Excellent Compatibility
Fully miscible with hydrocarbon oils without affecting the oil's viscosity or color.
Multifunctional
Combines antioxidant, anti-ozonant, free radical scavenging, and desulfurization properties.
Application Areas
1. Petroleum Additives
- Antioxidant for high-olefin gasoline (cracking/pyrolysis): Inhibits gum formation from olefin oxidation and reduces combustion chamber deposits.
- Antioxidant and desulfurization agent for mineral, synthetic, and vegetable oils: Extends oil service life.
2. Rubber & Plastics
- General-purpose antioxidant and antiozonant for natural and synthetic rubber: Prevents cracking, embrittlement, and thermal aging.
- Inhibits thermo-oxidative degradation during plastic processing: Improves the weather resistance of finished products.
3. Dyes & Intermediates
- Synthesis intermediate for azo and reactive dyes: The amino group can participate in coupling and acylation reactions.
4. Others
- Antioxidant for lubricating oils and greases; component of gasoline detergents.
