There are many types of antioxidants with different functions. According to the main role of the antioxidant can be divided into anti-thermal oxygen aging antioxidant, anti-ozone aging antioxidant, harmful metal ions inhibitor, anti-fatigue antioxidant, anti-ultraviolet radiation antioxidant, etc., but each kind of antioxidant role is often not exclusive to a particular antioxidant.

Amine antioxidants have the most prominent protective effect, but also the earliest discovery, the most varieties of a class. Its main role is anti-thermal oxygen aging, anti-ozone aging, and copper ions, light and flexing aging protection also has a significant effect.

Phenolic antioxidants and other antioxidants are not as good as amine antioxidants for protection. It just has outstanding non-contaminating properties. As the protective effect of each antioxidant has its limitations, and the aging of rubber products in the actual use of the process is the result of a variety of factors. So a single antioxidant can not well meet the protection requirements of the product.

In natural rubber, styrene butadiene, nitrile, chloroprene, isoprene rubber, etc. on the heat, light, ozone, curvature and cracking aging has a good protective effect. Especially in neoprene rubber and food packaging, medical and health care products, rubber parts, light-coloured and bright-coloured rubber products, high-grade cable rubber materials, as well as polyether, high-grade lubricants industry varieties with other general-type antioxidant unparalleled advantages. Therefore, it is an ideal substitute for antioxidant A, D, RD, 246, 4010, SP, WH-02, and the recommended dosage is 0.5-2%.
