The selection of antioxidants must be considered and reasonably selected according to the aging properties of various rubber materials, anti-aging requirements and the characteristics of various antioxidants. Next, the rubber antioxidant manufacturer - Yechang Auxiliary is mainly based on its own experience and tells you the precautions when using rubber antioxidants for wires and cables.

(1) Some antioxidants have coloring effects and pollution on the rubber. Generally speaking, phenolic antioxidants have poor protective effect, but do not contaminate or contaminate very little. The amine antioxidants with higher protective effect will contaminate the rubber and cause severe discoloration. These oppositions should be taken into consideration when selecting them.

(2) When a rubber antioxidant is difficult to meet the requirements, two or more antioxidants should be used together to make it produce a harmonious effect and ensure the anti-aging effect.

(3) The amount of anti-aging agent should not exceed the solubility in rubber to avoid frost spray and contaminate the surface quality of rubber.

⑷ Because each antioxidant has different characteristics, and the aging function of different rubber formulations is different.

Therefore, an antioxidant that is effective for one rubber may be ineffective or even harmful to another. Therefore, the selection of rubber antioxidants must be considered and reasonably selected according to the aging properties of various rubber materials, anti-aging requirements and the characteristics of various antioxidants.

⑸ Amine antioxidants have adverse effects on rubber scorch; phenolic antioxidants can delay vulcanization, and should be paid attention to when selecting them.
