Features of Rubber Antioxidant 4020 6ppd

This product is a polluting antioxidant. In addition to its good anti-oxidation performance, it is also resistant to ozone, cracking and cracking, and inhibiting harmful metals such as copper and manganese. Its performance is similar to that of antioxidant 4010NA, but its toxicity and skin irritation are smaller than 4010NA, and its solubility in water is better than 4010NA (washing loss rate: 50% for 4010NA and 15-20% for 4020) . It can be widely used in the preparation of tires, tapes and many other industrial rubber products, generally in the amount of 0.5-1.5%. This product is not suitable for the production of light-colored products due to serious pollution. Antioxidant 4020 is one of the main varieties of p-phenylenediamine antioxidants. P-phenylenediamine anti-aging agent is a major and excellent variety commonly used in the rubber industry at home and abroad, and it is also the direction of anti-aging agent development in the future.


  • It is an antiager and antioxidant for natural rubber and synthetic rubber. It has excellent protection against ozone cracking and flex fatigue.
  • It has excellent anti-oxidation, anti-ozone, anti-curvature cracking and sun-breaking cracking. It has strong inhibitory effect on harmful metals such as copper and manganese, and is suitable for all kinds of synthetic rubber and natural rubber. It has good dispersibility in the rubber compound and softens the rubber compound, and has little effect on the vulcanization. It can be used in various rubber products such as tires, and also as a thermal oxygen stabilizer for polyethylene, polypropylene and acrylic resins.
