Antioxidant 4020
Antioxidant 4020 is a liquid-form rubber antioxidant, chemically identified as N,N'-Di-sec-butyl-p-phenylenediamine (DMPPD or 6PPD equivalent), with the molecular formula C18H24N2 and a molecular weight of 268.3966. It is engineered to protect natural and synthetic rubbers, including SBR, BR, and NBR, from oxidative and thermal degradation, particularly in dynamic applications such as tires and conveyor belts. The product is traded in bulk drums or Intermediate Bulk Containers (IBCs) for industrial use.
In rubber compounding, Antioxidant 4020 provides exceptional resistance to fatigue and ozone damage, making it ideal for components exposed to cyclic stress or outdoor environments. Typical industry specifications for DMPPD include a minimum purity of 95%, a density range of 0.92-0.95 g/cm³ at 20°C, and a flash point above 100°C, ensuring safe handling and consistent performance. Its liquid form allows for easy dispersion in rubber formulations without the need for pre-mixing or grinding.
The automotive and industrial rubber sectors are primary consumers of Antioxidant 4020, where it is used to extend the service life of tires, seals, and other high-wear components. Its compatibility with various processing techniques, including injection moulding and extrusion, makes it a versatile additive for manufacturers aiming to enhance product durability. Buyers should confirm the supplier’s ability to provide consistent batches and validate the product’s performance in their specific applications.
