antioxidantsand antiozonants - Akrochem
Antiozonants – are chemicals and / or waxes that “bleed” to the surface of a rubber article, to protect it against attack from ozone (O3). For long-term storage protection, some rubber articles are sealed with an exterior coating of wax or similar substance for additional protection against attack from ozone.

Get PriceWhat is akrochem antioxidant 12?
Antioxidant 12 by Akrochem is a sterically hindered, polymeric, phenol-type non-staining, non-discoloring antioxidant. It also functions as a stabilizer in polymers like neoprene, nitrile, styrene-butadiene, latex, natural- and synthetic polyisoprene. It inhibits the degradation of polymers due to heat and oxygen.
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.
Which polymers have antioxidants added to their latex phase?
Nitrile, SBR, polychloroprene and synthetic polyisoprene are examples of polymers that have antioxidants added to their latex phase of processing to protect them from oxidation. Natural rubber polymers normally do not need the addition of “polymer stabilizers” to be protected against oxidation.
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.
Does natural rubber have antidegradants?
Natural rubber already contains naturally occurring antioxidants that protect the polymer from oxidation. One of the key properties of antidegradants (antioxidants and /or antiozonants) is their solubility in the rubber matrix. The faster the rate of bloom, the less soluble the antidegradant is in the polymer system.
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.
