Tires endure immense stress throughout their operational life, from continuous friction and heat generation to environmental exposure like ozone and UV radiation. Without adequate protection, these factors lead to rapid degradation, compromising performance and safety. This is where advanced rubber additives become indispensable, particularly in enhancing tire durability and longevity.
Among the most critical additives, 6PPD, also known as Antioxidant 4020 (CAS 793-24-8), stands out as a paramount solution. This highly effective phenylene diamine antioxidant is a cornerstone for modern tire manufacturing. It offers comprehensive protection against the primary causes of rubber aging. The use of 6PPD antioxidant for tire manufacturing is not merely an option but a necessity for producing high-quality, durable tires.
6PPD works by scavenging free radicals and deactivating pro-degradative metal ions, providing superior resistance to ozone cracking, thermal oxidation, and flex fatigue.
