Antioxidant 2246 CAS 119-47-1, also known as antioxidant 2246, is an antioxidant used in plastic and rubber products. It is one of the better varieties of phenolic antioxidants and has excellent protective effects on thermal oxidation, weather aging, flexural aging, and variable valence metals. It is suitable for light and colored rubber products. In the plastic industry, it has a protective effect on the thermal and light aging of chlorinated polyether, impact resistant PS, ABS resin, polymethyl ether, and fiber resin. Belongs to hindered phenolic antioxidants.

Physical and chemical properties

Antioxidant 2246, also known as antioxidant 2246, chemically named 2,2 ‘- methylene bis (4-methyl-6-tert-butylphenol), is a white or milky white crystalline powder with a melting point of 125-133 ℃; Density 1.04-1.09, soluble in organic solvents such as ethanol, acetone, benzene, petroleum ether, and insoluble in water; Slightly phenolic odor; This product is non-toxic and has good storage safety; This product turns slightly red after long-term storage, but it does not affect its antioxidant and anti-aging performance in oil, rubber, and plastic use

Product performance and purpose

This product belongs to a widely used and powerful hindered phenolic aldehyde antioxidant, which is pollution-free, non-toxic, and non coloring to the product. It has excellent protective effects on heat, oxygen, and cracking aging; Commonly used in white or bright colored rubber and plastic products (such as polyethylene, polypropylene, polyformaldehyde, ABS resin, and chlorinated polyether), especially for rubber products under sunlight, it has the greatest protective effect on aging, has no effect on vulcanization and plasticity, is easy to disperse in water, and is convenient to use.

This product has superior antioxidant and anti-aging properties. Compared with the same series of products antioxidant 264 (BHT, T501), through comparative experiments, it was found that in the formula that originally used antioxidant 264 (BHT, T501), only one-third of the amount of antioxidant 2246 (BHT, T501) needs to be used, which can achieve or even exceed the effect of the original antioxidant 264 (BHT, T501). If used in combination with UV absorbers UV-326-326, it will have superior synergistic effects. This product does not spray frost and has extremely low volatility, which can improve the weather resistance of the product. Suitable for various rubber, plastic, synthetic resin, latex, petroleum products, etc.

This product can be used as an antioxidant additive for petroleum products, with good oil solubility, good antioxidant effect, and less volatile loss.

This product is widely used in industries such as polypropylene, polyethylene, polystyrene, polyvinyl chloride, chlorinated polyether, ABS, paraformaldehyde, polyamide, etc. It is suitable for almost all polymers.
