Antioxidant 6PPD (N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine)
CAS Number: 793-24-8
6PPD is the world's most widely used rubber antidegradant, providing outstanding protection against ozone, flex cracking, and dynamic fatigue in tire compounds. It functions by scavenging ozone and reacting with peroxy radicals, effectively preventing the oxidative degradation of diene rubbers. 6PPD is an industry standard antiozonant in tire treads, sidewalls, and general dynamic rubber applications.
