Uses of Antioxidant 2246

2,2'-Methylene bis (4-methyl-6-tert-butylphenol) (CAS No.: 119-47-1), often referred to as Antioxidant 2246, is a phenolic antioxidant with excellent performance and is widely used in many fields:

1. Plastics industry: As a highly efficient antioxidant, it is widely used in a variety of plastic materials such as polyethylene, polypropylene, polystyrene, ABS resin, etc. In the plastic processing process, such as extrusion, injection molding, blow molding, etc., due to the effects of high temperature and shear force, plastic molecules are prone to oxidative degradation, resulting in a decrease in material performance. Antioxidant 2246 can effectively capture free radicals generated during the processing and use of plastics, terminate the oxidation chain reaction, prevent plastic aging, yellowing, embrittlement and other problems, improve the thermal stability, weather resistance and mechanical properties of plastics, and extend the service life of plastic products. For example, in polypropylene products, the addition of antioxidant 2246 can significantly improve its antioxidant properties in high temperature environments.

2. Rubber industry: Applicable to natural rubber and synthetic rubber, such as styrene-butadiene rubber, butadiene rubber, chloroprene rubber, etc. During the processing and use of rubber, it is susceptible to factors such as oxygen, ozone, heat, and light, and aging occurs, and phenomena such as hardening, brittleness, and cracking occur. Antioxidant 2246 can effectively inhibit the oxidative degradation and ozone aging of rubber, improve the fatigue resistance and flexural resistance of rubber, maintain the elasticity and flexibility of rubber products, and extend their service life. It is commonly used in rubber products such as tires, rubber tubes, and rubber seals.

3. Coating and ink industry: In coating and ink systems, antioxidant 2246 can prevent organic components such as resins from oxidizing and deteriorating during storage and use, and avoid problems such as crusting, discoloration, and performance degradation. It can improve the stability of coatings and inks, improve their drying performance, glossiness, and adhesion, and at the same time enhance the weather resistance and durability of coatings and ink films, making them less likely to fade, powder, or fall off after long-term exposure to the environment.

4. Adhesive and sealant industry: It can be used as an antioxidant additive in various adhesives and sealants, such as hot melt adhesives, pressure sensitive adhesives, silicone sealants, etc. It can effectively inhibit the oxidation reaction of adhesives and sealants during storage and use, prevent their performance from deteriorating, maintain good adhesion and sealing performance, extend the service life of the product, and ensure reliability under various environmental conditions.

5. Lubricant and fuel oil industry: Adding it to lubricants and fuel oils can effectively inhibit the oxidation of oil products, prevent the formation of oxidation products such as sludge and paint film, maintain the cleanliness and lubrication performance of oil products, reduce equipment wear and corrosion, and extend the maintenance cycle and service life of equipment. In fuel oil, it can also improve the stability of the fuel, prevent oxidation and deterioration during storage and transportation, and ensure the combustion performance of the fuel.

6. Other fields: In some special fine chemical products and polymer materials, antioxidant 2246 is also used as an antioxidant additive, such as in some fiber materials, electronic materials, medical polymer materials, etc., to improve the antioxidant properties of materials and stabilize product quality. In addition, it can also be used as an organic synthesis intermediate to prepare other compounds with special properties.
