Antiozonant

An antiozonant, also known as anti-ozonant, is an organic compound that prevents or retards damage caused by ozone.

A number of research projects study the application of another type of antiozonants to protect plants as well as salmonids that are affected by the chemicals.

Many elastomers are rich in unsaturated double bonds, which can react with ozone present in the air in process known as ozonolysis.

Ground-level ozone is naturally present, but it is also a product of smog and thus degradation is faster in areas of high air pollution.

All of these factors make vehicle tires particularly vulnerable, as they contain a high level of unsaturated groups, operate in areas prone to air pollution and are subjected to significant mechanical stresses.
