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.
Stable rubber composition providing protection against ozone
A rubber composition having good resistance to ozonization properties, in particular without the need to use 6PPD. This rubber composition is suitable for use in rubber articles, including in particular vehicle tires, such as rubber pneumatic tires, solid tires and non-pneumatic tires, and also general rubber products exposed to continuous and intermittent dynamic operating conditions and requiring protection from ozonization, like belts, hoses, cables, automotive mountings and bushings. In the rubber composition, the anti-ozonant compound is a partially hydrogenated quinoline derivative having formula (I) and serves to protect the rubber composition from ozonization and the consequent damaging effects caused by ozonization on the rubber composition.
