Compounding ingredient used to retard deterioration caused by ozone.
antiozidant. Substances that reverse or prevent severe oxidation by ozone. Antiozonants are added to rubber to prevent them from becoming brittle as atmospheric ozone reacts with them over time. Aromatic amines are often used as antiozonants.
a chemical which prevents or retards the attack of ozone on the surface of many elastomers (some chemicals will act to a certain extent to block both oxygen and ozone, although usually the activity is far more effective against one or the other)
Additive used to protect a polymer against the effects of ozone-induced degradation and hence used mainly in diene rubbers. Works either by providing a physical barrier to ozone penetration by forming a thin surface film of an ozone-resisting wax or by chemically reacting with ozone or polymer ozonolysis products, as do aromatic diamines such as p-phenylene diamine derivatives.
Any substance that slows the severe oxidizing effect of ozone on elastomers. Exposure to ozone typically causes surface cracking in many rubbers.
A substance that slows the appearance of cracks from the action of ozone when the elastomer is exposed under tension to air containing ozone.
