What are antioxidants & antiozonants in rubber compounding?

Both antioxidants and antiozonants are crucial additives in rubber compounding processes. They help maintain the integrity and performance of rubber materials, increasing their resistance to aging, cracking, and degradation caused by oxidation and ozone exposure.

What Antiozonants are used in rubber compounding?

Common antiozonants used in rubber compounding include waxes, fatty acids, and chemical compounds like paraphenylene diamine (PPD). Both antioxidants and antiozonants are crucial additives in rubber compounding processes.

Why do we need antioxidants for rubber composites?

Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.

How does rubber antioxidant work?

To prolong the service life of rubber composites by retarding their aging processes, rubber antioxidant initially relies on the use of a coating, such as paraffin, and coal tar, to physically isolate oxygen, but this protective layer would quickly lose the utility due to wear.

How do antiozonants protect rubber from ozone-induced degradation?

Antiozonants, also known as antiozonants or antiozonants, are added to rubber formulations to protect against ozone-induced degradation. Antiozonants function by creating a protective barrier on the rubber’s surface, preventing ozone from reaching the underlying rubber molecules.

What are the future trends of rubber antioxidants?

The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
