　　Characteristics and uses As an antioxidant, it is suitable for polyolefin, polyester, polystyrene, ABS resin and polyvinyl chloride. It is also suitable for white, brilliant or transparent products.

　　Antioxidant 300 is a typical thiobisphenol antioxidant. Due to its special structure, it has the dual functions of free radical terminator and hydroperoxide decomposer. The excellent synergistic effect is unmatched by commonly used antioxidants.

　　This product is a high-efficiency main antioxidant for rubber, polyolefin, plastic and other products, especially as an antioxidant for polyethylene cable and wire materials. Therefore, this kind of antioxidant is widely used in cable and wire industries at home and abroad.

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

　　The use of 300 antioxidants in polyethylene has the following advantages: better maintain the physical properties of its raw materials, (such as tensile strength, elongation, melt index, etc.); well preserve its electrical properties; a high degree of heat Stability; enhances the weather resistance of the product; anti-aging effect is four times the effect of general anti-aging agents; less volatile than other commonly used antioxidants; has a special synergistic effect when shared with carbon black.

　　Storage and packaging

　　Antioxidant 300 is stable in nature and has no special storage requirements. Avoid high temperatures and humidity during storage. Packed in cardboard drum lined with plastic bag, net weight 25kg/drum. Can also be designed according to customer requirements.
