What is the anti-aging agent of rubber?

Anti-aging agent BLE，In the natural rubber and synthetic rubber such as neoprene, butyronitrile, butylbenzene, 3-polybutadiene rubber and the rubber latex , Antioxidant BLE may serve as the general antioxidant. It also has the good property to protect from the heat, oxygen, ozone, climate and deflection and so on .

What is rubber antioxidant TMQ TDQ Rd?

Rubber Antioxidant TMQ, TQ, TDQ, RD: It is a very important category of rubber antioxidants. It has a good powerful effect on heat, oxygen, and fatigue aging.

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 happened to natural rubber elastomeric polymer?

Natural rubber was the only elastomeric polymer available for commercial use at that time. Articles made from natural rubber would soon become soft and tacky. They would no longer be serviceable. Chemists determined the cause of degradation and pre-mature failure of rubber articles was due to reaction with oxygen in the atmosphere.

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.

Why do antioxidants react with hydrocarbon radicals?

Antioxidants (and antiozonants) react with these radicals to terminate the chain reaction causing oxidation of polar polymer systems; thereby prolonging the serviceability of a rubber article. Antioxidants also react with hydrocarbon radicals when they are formed.
