Irganox 1098 is a high-performance antioxidant with the CAS number 23128-74-7. It is supplied directly from the factory, ensuring high - quality and competitive pricing. Chemically, it belongs to the class of hindered phenolic antioxidants. This product is a white to off - white powder with a melting point typically in the range of 156 - 161°C. It has good solubility in common organic solvents such as acetone, chloroform, and ethyl acetate, but is insoluble in water. Its molecular formula is C42H52N2O4, and its molecular weight is approximately 652.88 g/mol. Irganox 1098 provides excellent long - term thermal stability and resistance to oxidation, which makes it a popular choice in various industries.
Irganox 1098 is mainly used to prevent the oxidation of polymers, such as polyamides (PA), polyesters (PET, PBT), and polyolefins (PP, PE). In the polyamide industry, it can effectively improve the heat - aging resistance of nylon fibers and engineering plastics, which is crucial for applications in automotive engine compartments, electrical connectors, and mechanical parts. In the case of polyesters, it helps to maintain the physical and mechanical properties of the material during long - term use at elevated temperatures, making it suitable for use in packaging films, fibers for clothing, and industrial yarns. Additionally, it can be used in adhesives and sealants to prevent oxidation - induced degradation, extending their service life.
When using Irganox 1098, it is recommended to mix it uniformly with the polymer matrix. For most applications, the typical dosage ranges from 0.1% to 1.0% by weight, depending on the specific polymer, processing conditions, and the desired level of antioxidant protection. In the extrusion process of polymers, Irganox 1098 can be added directly to the polymer pellets before feeding them into the extruder. In the injection - molding process, it should be pre - blended with the polymer raw materials thoroughly to ensure homogeneous dispersion. It can also be used in combination with other additives such as light stabilizers and processing aids to achieve comprehensive protection of the polymer product.
Automotive Industry: A major automotive parts manufacturer was facing issues with the degradation of nylon engine covers due to high - temperature exposure and oxidation. They incorporated Irganox 1098 into their nylon formulation at a dosage of 0.5% by weight. After extensive testing, it was found that the engine covers showed a significant improvement in heat - aging resistance. The parts maintained their mechanical strength and dimensional stability even after long - term exposure to high temperatures under the hood, reducing the rate of product failure and increasing customer satisfaction.
Textile Industry: A textile company producing polyester fibers for outdoor clothing was dealing with the problem of yellowing and loss of strength of their products over time. By adding Irganox 1098 at a concentration of 0.3% during the fiber - spinning process, the fibers exhibited better resistance to oxidation and photo - degradation. The clothing made from these fibers retained its color and mechanical properties for a longer period, enhancing the overall quality and durability of the products.
