Properties and Usage:

Antioxidant 2246, chemical name: 2,6-di-tert-butyl-4-methylbenzene, is a powerful antioxidant, mainly used in plastics, rubber, lubricants, coatings, food and cosmetics.

1. Plastic and rubber industry:

Antioxidant 2246 is used in the production of plastics and rubber materials such as polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP). It can effectively improve the heat resistance and aging resistance of plastics and rubber, and prevent material degradation caused by oxidation reactions.

2. Lubricants and fuels:

In lubricants, hydraulic oils and other oils, antioxidant 2246 can prevent oil degradation due to oxidation, maintain its good lubricity and high temperature performance.

3. Food and cosmetics:

In the field of food and cosmetics, antioxidant 2246 is often used to prevent the oxidation of fats and oils. It can effectively inhibit the oxidation of fatty acids in food and prevent taste and deterioration; for cosmetics, antioxidant 2246 helps to delay the oxidation of ingredients and maintain the stability and effectiveness of the product.

4. Coatings and paints:

Antioxidant 2246 can also be used in coatings and paints to prevent oxidation and discoloration, and extend the service life of the coating.

5. Cables and wires:

In the manufacture of cables and wires, antioxidant 2246 can effectively prevent oxidation damage, especially in high temperature or humid environments, ensuring the conductivity, safety and durability of the cables.

Storage conditions: Preserve in well-closed, light-resistant and airtight containers

Packing: This product is packed in 25kg bag, and it can also be customized according to customers' requirements
