1. As general-purpose phenolic antioxidant. Widely used in polymer materials, petroleum products and food processing industry. This product is commonly used as rubber antioxidant. It has a certain protective effect on heat and oxygen aging, and can also inhibit copper damage. It has no anti-ozone ability alone, but it can protect the damage of vulcanized rubber with anti-ozone agent and wax. It can also be used as gelling inhibitor in styrene butadiene rubber. The general dosage in rubber is 0.5-3 parts. When the dosage is increased to 3-5 parts, it will not spray frost. It can also be used as a stabilizer in the post-processing and storage of synthetic rubber, and can be used in styrene butadiene rubber, butadiene rubber, ethylene propylene rubber, chloroprene rubber and other rubber types. Antioxidant 264 is an effective antioxidant in some polymer materials. It is an effective stabilizer in polyethylene, polyvinyl chloride (dosage 0.01-0.1%) and polyvinyl ether. Antioxidant 264 is an excellent antioxidant additive for various petroleum products. Good oil solubility. This product can also be used as an antioxidant for food processing industry, used in foods containing more oil and grease. The dosage in grease, butter, dried fish and shellfish products, fish and shellfish salt cured products, whale meat frozen products, etc. is less than 0.2g/kg, and less than 0.75g/kg in chewing gum. The usage of this product is dipping method, direct mixing method, mixing method after dissolving in ethanol and spraying method, etc. The United States, Japan and the European Community have used this product as a legal feed additive, and the European Community stipulates that the maximum amount in the feed is 150ppm, which can be used in various feeds.

2. BHT is an oil-soluble antioxidant widely used at home and abroad. Although more toxic, but its antioxidant capacity, heat resistance and stability, neither specific odor, and no metal ion color reaction and other shortcomings, and low price, only 1/5 ~ 1/8 of BHA, China is still used as the main antioxidant. Generally used with BHA, and citric acid or other organic acids as synergists. It can be used in edible fats and oils, fried foods, cookies, instant noodles, instant rice, canned nuts, dried fish products and cured meat products, the maximum use level is 0.2g/kg.

3. One of the general-purpose phenolic antioxidants. Used as a non-polluting antioxidant, it can effectively inhibit air oxidation, thermal degradation and copper damage, etc. It can be used as antioxidant and heat stabilizer for polyolefin, polyester, polystyrene, ABS resin, polyvinyl chloride, cellulose resin, etc. It is used as antioxidant and anti-deterioration agent for natural rubber and synthetic rubber such as butyl, butyl, chloroprene, nitrile, ethylene propylene and satin in rubber industry. It is also used as antioxidant for petroleum products, EVA type hot melt adhesive, unsaturated fatty acid coatings, etc. Food-grade di-tert-butyl-p-cresol is allowed to be used as food antioxidant, which can be used in fats, baked goods, fried foods, cereals, dairy products, meat products and preserves. It can also be used as antioxidant for cosmetics, spices, feed, etc. In addition, it can also be used as lubricant and fuel oil additives to improve the stability of oil products. The dosage is usually 0.05%~1.0%.
