Due to the limitation of the protective effect of each kind of anti-aging agent, and the aging of rubber products in actual use is the result of a variety of factors, so the selection of anti-aging agent should pay attention to the following points:

(1) due to the different characteristics of each anti-aging agent, and the aging performance of different rubber formula is different.Therefore, the most effective anti-aging agent for one rubber, may be ineffective or even harmful to another rubber.Therefore, the selection of anti-aging agent must be based on the aging properties of all kinds of rubber, anti-aging requirements and the characteristics of all kinds of anti-aging agent consideration, reasonable choice.

1. Antioxidant BHT can inhibit or delay the oxidative degradation of plastic or rubber and prolong its service life.

2. The antioxidant BHT can prevent the acid value or viscosity of the lubricating oil and fuel oil from rising.

3, antioxidant BHT is a synthetic rubber (butylbenzene, nitrile, polyurethane, cis, etc.), polyethylene, polyvinyl chloride stabilizer, antioxidant BHT is a commonly used phenolic antioxidant in rubber, anti-oxidation BHT has protective effect on thermal rubber aging of natural rubber, cis-butyl, butylbenzene, butyl, isoprene, nitrile, ethylene-propylene and other synthetic rubbers, acrylates and latex products. Antioxidant BHT can inhibit copper damage. It is compatible with ozone and wax and various factors that can prevent weathering. This product is easy to disperse in rubber. The antioxidant BHT can be directly mixed into rubber or added to the latex as a dispersion. It can be used to make sidewalls of tires, white, bright and transparent colors of various rubber and dairy products, and daily use. Medical hygiene, tape, rubber shoes and food products rubber products, antioxidant BHT can also be used as a stabilizer for post-treatment and storage of synthetic rubber.

4. The solubility of antioxidant BHT is: ethanol 0.5% (20), soybean oil 30% (25), cottonseed oil 20% (25), lard 40% (40).

5. Antioxidant BHT as a food additive can delay the rancidity of food. The antioxidant BHT is used in animal and vegetable oils and fats and foods containing animal and vegetable oils and fats. In addition, the antioxidant BHT can also be used in the inks, adhesives, leather, casting, printing, coatings and electronics industries.

6. Antioxidant BHT is also a stabilizer for cosmetics and medicine. The amount of antioxidant BHT added: 0.01% - 2%.

7. Antioxidant BHT is an excellent anti-oxidant additive for various petroleum products. Antioxidant BHT has the best anti-oxidation effect when its working temperature is 100 degrees. Antioxidant BHT is widely used in turbine oil, transformer oil, hydraulic oil, heat transfer oil, brake oil, spindle oil and precision mechanical oil, paraffin wax anti-adhesive. The antioxidant BHT can be added to the product either directly or in a mother liquor. In order to improve the product's antioxidant performance and extend its service life. Antioxidant BHT is compounded with long-chain alkaline ZDDP and TCP metal deactivated rust inhibitor to prepare anti-wear hydraulic oil and other products. The dosage is generally 0.1-1%.
