Properties: antioxidant 300 is a typical thiobisphenol antioxidant.Due to the particularity of its structure, it has the dual functions of free radical terminator and hydroperoxides decomposer. When it is Shared with carbon black, it shows excellent synergistic effect, which is incomparable to common antioxidants.

Application: antioxidant 300 is an efficient and multi-functional sulfur-containing hindered phenolic antioxidant, which has the dual function of primary and secondary antioxidant and has a good synergistic effect when used in conjunction with carbon black.Widely used in plastics, rubber, rosin resin and petroleum products.Especially suitable for polyethylene wire and cable materials (such as communication cable sheath materials, insulation materials, chemical cross-linked polyethylene insulation materials, semi-conductive shielding materials, silane cross-linked polyethylene cable materials) and high-density polyethylene pipe materials, outdoor use of other black polyethylene materials.

Packing: 25kg paper and plastic composite bag.

Storage: store in a cool, dry and well-ventilated place.The packaged products should avoid direct sunlight and be valid for 1 year.
