Antioxidant 4020 (6PPD)
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.

Sourcing Antioxidant 4020 (6PPD) from Qingdao Rensheng Huida Trading Co., Ltd - China Import Guide
Prior to ordering, confirm that Antioxidant 4020 (6PPD) meets your required specifications, including CAS number 793-24-8 and assay purity. Request a COA to verify compliance with industry standards such as ASTM D4676. If intended for regulated applications, ensure the supplier can provide relevant certifications for safety and environmental compliance, such as REACH or RoHS.
Clarify logistics details, including lead time, which may vary between 20 to 45 days for bulk shipments from Qingdao. Common Incoterms for chemical exports include FOB Qingdao or CIF to the destination port. Payment terms often involve a 30% deposit via T/T, with the balance due upon shipment. Agree on these terms in a written contract to avoid misunderstandings.
Upon delivery, inspect the packaging for signs of damage or moisture contamination, as 6PPD is hygroscopic. Conduct quality checks by testing the assay, melting point, and solubility in your intended rubber formulation. For long-term storage, keep the product in its original packaging under controlled conditions to prevent degradation. Request third-party inspection reports if available for additional assurance.
