Product Introduction
6PPD is a high-performance p-phenylenediamine rubber antioxidant and antiozonant widely used in tires, industrial rubber products, elastomers, conveyor belts, hoses, cables, and automotive rubber components.
Chemically known as N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine, 6PPD is designed to protect rubber materials against ozone cracking, thermo-oxidative degradation, flex cracking, and environmental aging.
Due to its excellent balance of antioxidant, antiozonant, and fatigue-resistance performance, 6PPD is one of the most widely used protective additives in tire compounds and high-performance rubber formulations.
Chemical Properties and Reaction Mechanism
6PPD functions primarily as a rubber antioxidant, antiozonant, and anti-aging stabilizer.
In rubber systems:
- Scavenges free radicals generated during oxidative degradation
- Reacts with atmospheric ozone, helping suppress ozone-induced surface cracking
- Inhibits thermal oxidation and flex fatigue deterioration
- Improves durability under dynamic mechanical stress conditions
Key stabilization features:
- p-Phenylenediamine antioxidant structure
- Strong anti-ozone protection capability
