Vulkanox 4020 is a rubber antioxidant based on N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD). It is supplied in brownish lentil-shaped granules and is widely used in rubber compounding to protect elastomers against oxidative and ozone-related degradation during processing and service life.
This amine-type antioxidant is commonly incorporated into natural rubber (NR) and synthetic rubber formulations to enhance resistance against heat, oxygen, and dynamic stress exposure. It is suitable for applications where rubber components are subjected to mechanical strain and environmental exposure. Vulkanox 4020 is typically used in tyre compounds, industrial rubber goods, conveyor belts, and automotive rubber parts.
The product is supplied in standard industrial packaging and is intended for use in rubber processing operations under controlled compounding conditions. Users should consult technical data and safety documentation before industrial application.
