Antioxidants play a crucial role in various industries, protecting materials from oxidative degradation and extending their lifespan. Among them, Antioxidant 1330 is a well - known and widely used antioxidant. In this blog, as a supplier of Antioxidant 1330, I will delve into the molecular weight of Antioxidant 1330 and its significance in the context of its applications.
Understanding Antioxidant 1330
Antioxidant 1330, also known as 1,3,5 - tris(3,5 - di - tert - butyl - 4 - hydroxybenzyl) - 1,3,5 - triazine - 2,4,6(1H,3H,5H) - trione, is a high - molecular - weight hindered phenolic antioxidant. It is commonly used in polymers, such as polyolefins, to prevent the oxidation of the polymer chains. Oxidation can lead to a variety of problems, including loss of mechanical properties, discoloration, and reduced service life of the polymer products.
Molecular Weight of Antioxidant 1330
The molecular formula of Antioxidant 1330 is (C_{48}H_{69}N_{3}O_{6}). To calculate the molecular weight, we need to consider the atomic weights of each element in the molecule.
The atomic weight of carbon (C) is approximately 12.01 g/mol, hydrogen (H) is about 1.008 g/mol, nitrogen (N) is around 14.01 g/mol, and oxygen (O) is approximately 16.00 g/mol.
For the 48 carbon atoms in Antioxidant 1330, the total mass contributed by carbon is (48\times12.01 = 576.48) g/mol.
The 69 hydrogen atoms contribute (69\times1.008 = 69.552) g/mol.
The 3 nitrogen atoms contribute (3\times14.01 = 42.03) g/mol.
The 6 oxygen atoms contribute (6\times16.00 = 96.00) g/mol.
The molecular weight of Antioxidant 1330 is the sum of these contributions: (576.48+69.552 + 42.03+96.00=784.062) g/mol.
Significance of Molecular Weight
The relatively high molecular weight of Antioxidant 1330 has several important implications for its performance and applications.
Low Volatility
High - molecular - weight antioxidants like Antioxidant 1330 have low volatility. This is especially important in high - temperature processing applications. When polymers are processed at elevated temperatures, low - volatility antioxidants are less likely to evaporate, ensuring that they remain in the polymer matrix to provide long - term protection against oxidation. For example, in the extrusion or injection - molding of polyolefins, where temperatures can reach several hundred degrees Celsius, Antioxidant 1330 stays in the polymer, preventing oxidative degradation during and after processing.
Migration Resistance
Antioxidant 1330's high molecular weight also gives it good migration resistance. In polymer blends or multi - layer structures, antioxidants with low migration are preferred. They are less likely to move from one polymer phase to another or to the surface of the material. This is crucial in applications where the integrity of the antioxidant protection needs to be maintained throughout the material. For instance, in food - contact polymers, migration of antioxidants to the food can be a concern. Antioxidant 1330's low migration characteristics make it a suitable choice for such applications.
Long - Term Stability
The high molecular weight contributes to the long - term stability of the antioxidant. It is less prone to degradation itself, which means it can provide effective antioxidant protection over an extended period. This is beneficial for applications where the polymer products are expected to have a long service life, such as in outdoor applications, automotive parts, and electrical insulation.
Comparison with Other Antioxidants
There are many other antioxidants available in the market, each with its own characteristics. Let's compare Antioxidant 1330 with some other common antioxidants.
Water Soluble Antioxidant
Water - soluble antioxidants are designed for applications where the antioxidant needs to be dispersed in an aqueous environment. In contrast, Antioxidant 1330 is non - water - soluble and is mainly used in non - polar polymer matrices. Water - soluble antioxidants are often used in food and beverage applications, cosmetics, and some water - based coatings. The difference in solubility and molecular structure between Antioxidant 1330 and water - soluble antioxidants leads to different application scenarios.
Antioxidant K300
Antioxidant K300 may have a different chemical structure and molecular weight compared to Antioxidant 1330. The performance of these two antioxidants can vary depending on the specific polymer system and processing conditions. For example, Antioxidant K300 may have different levels of volatility, migration resistance, and antioxidant efficiency. The choice between the two depends on the requirements of the end - use application, such as the desired level of protection, processing temperature, and cost.
Antioxidant 245
Antioxidant 245 is another widely used hindered phenolic antioxidant. However, it has a lower molecular weight compared to Antioxidant 1330. The lower molecular weight of Antioxidant 245 may result in higher volatility and less migration resistance. Antioxidant 245 is often used in applications where a faster - acting antioxidant is required, or in systems where the processing temperatures are relatively low.
Applications of Antioxidant 1330
Antioxidant 1330 is used in a wide range of industries and applications.
Polyolefin Industry
In the polyolefin industry, which includes polyethylene and polypropylene, Antioxidant 1330 is used to improve the thermal stability and oxidative resistance of the polymers. It helps to prevent the yellowing and embrittlement of polyolefin products during processing and long - term use. This is important for products such as plastic pipes, films, and fibers.
Rubber Industry
In the rubber industry, Antioxidant 1330 can be used to protect rubber compounds from oxidation. It helps to maintain the mechanical properties of rubber products, such as tires, seals, and gaskets, over time. Oxidation can cause rubber to harden, crack, and lose its elasticity, and Antioxidant 1330 can mitigate these effects.
Electrical and Electronic Industry
In the electrical and electronic industry, Antioxidant 1330 is used in insulation materials. It helps to prevent the oxidation of the insulation polymers, ensuring the long - term performance and safety of electrical and electronic devices. Oxidative degradation of insulation materials can lead to electrical failures and safety hazards.
