Import Antioxidant 4020 (6ppd) — Buy in Bulk from Supplier in China

Antioxidant 4020, also known as 6PPD (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine), is a rubber antiozonant and antioxidant used to protect elastomers from ozone cracking and oxidative degradation. This compound is critical in extending the lifespan of rubber products exposed to dynamic stress and environmental factors. Its chemical structure allows it to form a protective layer on the rubber surface, preventing ozone from attacking the polymer chains.

The additive is typically supplied as a dark brown to black flake or granular solid, with a minimum purity of 95% as per industry standards. It is highly soluble in organic solvents and compatible with natural rubber, synthetic rubber (e.g., SBR, BR), and their blends. Standard grades of 6PPD often meet ASTM D4676 or equivalent specifications for performance in tire and industrial rubber applications.

Antioxidant 4020 is primarily used in the tire manufacturing industry, as well as in conveyor belts, hoses, and seals where resistance to ozone and flex fatigue is essential. It is traded in 25 kg multiwall paper bags or 500 kg big bags, with buyers confirming packaging, MOQ, and lead times directly with the supplier. The product’s effectiveness is maximized when combined with wax-based antiozonants for comprehensive protection.
