Characteristics and uses:

As an antioxidant, Antioxidant 330 is suitable for the polyolefine, polyester, polystyrene, ABS resin, polyvinyl-chloride and so on. And also is 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 1,3,5-Trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene is to be used together with the carbon black, it shows outstanding synergistic effect for which other commonly used antioxidants are unable to compare with.
Antioxidant 300 is the high efficiency main antioxidant of rubber, polyolefine, plastic and so on products. Especially when irganox 330 is used as the antioxidant of the polyethylene cable electrical wire material, its effect is outstanding. So in both domestic and foreign cable electrical wire industry, antioxidant 300 is widely used.
When this antioxidant is used for the polyethylene food packing material, its limited use level is: low density polyethylene: 0.05%; high density polyethylene: 0.25%.
Adopt the Antioxidant 300 in the polyethylene has the following advantages:

Better keep 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.

Storing and packing:

Antioxidant 300 has stable property, has no special requirement to the storage. When store up, avoid high temperature and dampness. Use cardboard drum inner lining plastic bag, net weight 25kg/drum. Or design according to customer demand.
