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