Anti-aging agent 2246

　　Anti-aging agent 2246 is an antioxidant used in plastic and rubber products. It is one of the better varieties of phenolic antioxidants. It has protection against thermal oxygen, weather aging, flexural aging, and protection against variable-value metals. Excellent, suitable for light-colored and colored rubber products. In the plastics industry, it has a protective effect on thermal aging and photoaging of chlorinated polyether, impact-resistant PS, ABS resin, polymethyl ether, and fiber resin. It is a hindered phenolic antioxidant.

　　CAS number 119-47-1

　　White or milky white crystalline powder

　　Melting point 125-133℃

　　Density 1.04-1.09

　　use

　　Mainly used for strong hindered phenol-aldehyde antioxidants, non-polluting, non-toxic, non-colored to products, and has excellent protection against heat, oxygen, cracking and aging; often used for white or brilliant rubber and plastic products Medium (polyethylene, polypropylene, polyoxymethylene, ABS resin, chlorinated polyether, etc.), especially for the aging of rubber products under sunlight, it has no effect on vulcanization and plasticity, and is easily dispersed in water , Easy to use.

　　Compared with antioxidant 264 (BHT, T501) of the same series, this product has excellent antioxidant and anti-aging properties. It can be obtained through comparison test that in the original formula using antioxidant 264 (BHT, T501), only the use Antioxidant 264 (BHT, T501) A third amount of antioxidant 2246 can achieve or even exceed the effect of the original antioxidant 264 (BHT, T501). If it can be used together with ultraviolet absorber UV-326-326, it will exert superior synergistic effect. This product does not spray frost and has very low volatility, which can improve the weather resistance of the product. Suitable for a variety of rubber, plastic, synthetic resin, latex, petroleum products, etc.

　　This product can be used as an antioxidant additive for petroleum products. It has good oil solubility, good antioxidant effect, and is not easily volatile.

　　This product is widely used in polypropylene, polyethylene, polystyrene, polyvinyl chloride, chlorinated polyether, ABS, polyoxymethylene, polyamide and other industries, and has a good stabilizing effect on the thermal degradation of almost all polymers. The usual dosage is 0.1-1.0%. The dosage is 0.12-3% in ABS plastic. In rubber and plastic products, the dosage is 3-5%, and the dosage is about 0.075% when polypropylene is granulated. If it is used together with antioxidant DLTP, the dosage is 0.075%, and the finished product will have better anti-aging properties.
