Combined with the relevant background of rubber materials you focused on earlier, the common antioxidants used in rubber are as follows:
1.
Amine Antioxidants
Represented by 6PPD, IPPD and TMQ, they have excellent anti-ozone and anti-thermal oxygen aging effects, and are widely used in tires, rubber hoses and other heavy-duty rubber products.
2.
Phenolic Antioxidants
Mainly including 264, 1010 and 1076, they are non-polluting and non-discoloring, suitable for light-colored, transparent rubber products and food-contact rubber accessories.
3.
Thioester & Phosphite Antioxidants
Typical products such as DLTP and TNP are often used as auxiliary antioxidants, which can synergize with main antioxidants to significantly improve the long-term anti-aging performance of rubber.
