Antiozonant

An antiozonant, also known as anti-ozonant, is an organic compound that prevents or retards the degradation of material caused by ozone (ozone cracking). Antiozonants are used as additives to plastics and rubber, especially in tire manufacturing.^[1]

Common antiozonants include:

• p-Phenylenediamines such as 6PPP (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine)^[2] or IPPD (N-isopropyl-N'-phenyl-p-phenylenediamine)^[3]
• 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline (ETMQ)
• Ethylene diurea (EDU)
• Paraffin waxes that form a surface barrier.
