Uses: As an antioxidant, it is suitable for the polyolefine, polyester, polystyrene, ABS resin, polyvinyl chloride and so on. And also suitable for the white, bright colored or the transparent products. Antioxidant 300 is a typical thiobisphenol antioxidant. Because of its special structure, it has both the functions of free radical terminator and hydroperoxide decomposer. When it is used together with carbon black, it shows outstanding synergistic effect compared with other commonly used antioxidants. Especially it has outstanding effect in the polyethylene electrical cable.

When used for the polyethylene food packing material, the limits are: low density polyethylene: 0.05%; high density polyethylene: 0.25%.

Advantage of using antioxidant 300 in PE: Better keeping the raw material's physical properties( such as tensile strength, elongation rate, melt index, etc.); Can preserve its electrical property, high heat stability; Improve product's weathering resistance; Its ageing resistance effect is four times better than common aging-proof agents; Smaller volatility than other commonly used antioxidants; Special synergistic effect with carbon black.
