Antioxidant 300 is a typical thiobisphenol antioxidant. Due to its unique structure, it has the dual functions of a free radical terminator and a hydrogen peroxide decomposer. When used with carbon black, it exhibits excellent synergistic effects, which is incomparable to commonly used antioxidants.

This product is an efficient main antioxidant for rubber, polyolefin, plastic and other products, especially as an antioxidant for polyethylene cable and wire materials. Therefore, this antioxidant is widely used in the cable and wire industry both domestically and internationally.

When this antioxidant is used as an antioxidant for polyethylene food packaging materials, its limit is 0.05% for low-density polyethylene and 0.25% for high-density polyethylene.

The use of 300 antioxidants in polyethylene has the following advantages: better maintaining the physical properties of its raw materials, such as tensile strength, elongation, melt index, etc; Well preserved its electrical performance; High thermal stability; Enhance the weather resistance of the product; The anti-aging effect is four times that of general anti-aging agents; Less volatile than other commonly used antioxidants; There is a special synergistic effect when shared with carbon black.

Storage, transportation and packaging

Antioxidant 300 has stable properties and no special storage requirements. Avoid high temperature and humidity during storage. Packed in cardboard barrels lined with plastic bags, with a net weight of 25kg/barrel. It can also be designed according to customer requirements.
