Therefore, antioxidants that are most effective against a certain rubber material may not be effective or even harmful to another rubber material. Therefore, the selection of antioxidants must be based on the aging properties of various rubber materials, anti-aging requirements, and the characteristics of various antioxidants.
Second, when an anti-aging agent is difficult to meet the requirements, two or more anti-aging agents should be used together to make it a coordinating role to ensure anti-aging effects.
Third, some anti-aging agents have coloring and pollution on the rubber. In general, phenolic antioxidants have poor protection but do not pollute or pollute very little.
