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, EMQ, or Ethoxyquin)
- Ethylene diurea (EDU)
- Paraffin waxes that form a surface barrier [4]
