Rubber Antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend the Shelf life.
China is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. The production of rubber antioxidants in China ranged from 365,000 to 378,000 tons during 2016–2020, showing a constant annual trend. Amine antioxidants are the main rubber antioxidants produced and used in the World, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline(TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants. Moreover, the annual production of 6PPD is 189,500–208,600 tons, which accounts for about 55% of the total amount of amine antioxidants, followed by TMQ with an annual production of 102,800–126,000 tons (approximately 30% of the total amount).
Rubber Antioxidant are widely used in the manufacture of tyres, rubber compounding, plastic, adhesive tape, wires, cables and other rubber products.
