Antiozonant

Antiozonant

An antiozonant, also known as anti-ozonant, is a chemical compound that prevents or slows down the degradation of material caused by ozone gas in the air (ozone cracking). Antiozonants are used as additives to plastics and rubber, especially in tire manufacturing.

Common antiozonants include:

* Paraffin waxes that form a surface barrier
* "p"-Phenylenediamines such as 6PPP ("N"-(1,3-dimethylbutyl)-"N"'-phenyl-"p"-phenylenediamine) [ [http://www.chemicalland21.com/specialtychem/finechem/6PPD.htm 6PPP] ] or IPPD ("N"-isopropyl-"N"'-phenyl-"p"-phenylenediamine) [ [http://www.wrchem.com/Products/WESTCO_IPPD.htm IPPD] (product page)]
