Factory Supply Rubber Antioxidant 2246 with CAS number 119 - 47 - 1 is a high - quality antioxidant commonly used in the rubber industry. It has a good price, which makes it a cost - effective choice for many rubber manufacturers.
**Physical and Chemical Properties**:
- Appearance: Usually presents as a white or light yellow crystalline powder.
- Molecular Formula: C₁₅H₁₆O₂
- Molecular Weight: Approximately 228.29 g/mol
- Melting Point: Around 133 - 137°C
- Solubility: It is soluble in common organic solvents such as benzene, toluene, acetone, and ethanol, but insoluble in water.
This rubber antioxidant 2246 is mainly used in the rubber industry. It can effectively prevent the rubber from oxidizing, delaying the aging process of the rubber, and improving the service life and performance of rubber products. Here are some specific applications:
**Tire Manufacturing**: In tire production, antioxidant 2246 can protect the rubber from the damage of oxygen, ozone, and heat during the high - speed rotation of the tire and long - term exposure to the environment. This helps to maintain the elasticity and strength of the tire, reducing the risk of tire cracking and aging.
**Rubber Hoses and Seals**: For rubber hoses and seals used in automotive, industrial, and household appliances, antioxidant 2246 can enhance their resistance to oxidation, ozone, and heat. This ensures that the hoses and seals can maintain their sealing performance and mechanical properties in different environments, preventing fluid leakage and equipment failure.
The usage of Factory Supply Rubber Antioxidant 2246 is relatively simple. It can be added directly to the rubber compound during the mixing process. The following are the general steps:
**Mixing Preparation**: First, ensure that the rubber raw materials and other additives are prepared according to the formula requirements. The rubber should be in a suitable state for mixing, such as being plasticized to a certain degree.
**Addition of Antioxidant 2246**: Gradually add the antioxidant 2246 to the rubber compound during the mixing process. The addition amount usually depends on the type of rubber, the application environment, and the expected performance of the rubber product. Generally, the addition amount is in the range of 0.5 - 3 phr (parts per hundred rubber).
**Mixing Process**: After adding the antioxidant 2246, continue the mixing process to ensure uniform dispersion of the antioxidant in the rubber compound. This can be achieved through mechanical mixing equipment such as internal mixers or open - mill mixers.
**Case 1: Tire Manufacturer A**
Tire Manufacturer A was facing the problem of early aging and cracking of their tires, especially in high - temperature and high - humidity environments. After using Factory Supply Rubber Antioxidant 2246, they added 1.5 phr of the antioxidant to their tire rubber compound. Through long - term road tests and laboratory simulations, they found that the aging resistance of the tires was significantly improved. The service life of the tires increased by about 30%, and the cracking rate was reduced by more than 50%. This not only improved the quality of their products but also enhanced their market competitiveness.
**Case 2: Rubber Hose Manufacturer B**
Rubber Hose Manufacturer B produced rubber hoses for industrial equipment. They used to have issues with the hoses losing their flexibility and sealing performance over time due to oxidation. By incorporating 2 phr of antioxidant 2246 into their rubber formula, the hoses showed better resistance to oxidation and heat. In a real - world industrial application test, the hoses maintained their performance for a much longer time, reducing the frequency of hose replacement and saving maintenance costs for the end - users.
