The product, High Quality Antioxidant 702 with CAS number 118 - 82 - 1, is a high - performance antioxidant. The CAS number 118 - 82 - 1 uniquely identifies this chemical compound in the global chemical information system, ensuring its traceability and standardization.
In terms of quality, our Antioxidant 702 is of high - grade, meeting the strictest industry standards. The purity of the product is carefully controlled to ensure stable performance. It has a specific molecular structure that endows it with excellent antioxidant properties. Its physical state could be a powder or a fine crystalline form, depending on the manufacturing process and post - processing. The color is usually white or off - white, which indicates its high purity and lack of significant impurities.
Antioxidant 702 has a wide range of applications in various industries. In the polymer industry, it is used to prevent the oxidation of polymers such as polyolefins (polyethylene and polypropylene). Oxidation can lead to the degradation of polymers, resulting in reduced mechanical properties, discoloration, and a shorter service life. By adding our Antioxidant 702, the stability of polymers can be significantly improved, and the products can maintain their excellent performance over a long period.
In the rubber industry, it helps to protect rubber products from oxidative aging. Rubber products are often exposed to oxygen, heat, and light, which can cause them to harden, crack, and lose their elasticity. Antioxidant 702 can effectively slow down this aging process, extending the lifespan of rubber products such as tires, seals, and hoses.
It is also used in the lubricant industry. Lubricants are prone to oxidation during use, which can lead to the formation of sludge and varnish, reducing the lubricating effect and potentially damaging the equipment. Adding Antioxidant 702 to lubricants can enhance their oxidation resistance, ensuring smooth operation of machinery and reducing maintenance costs.
When using Antioxidant 702, it is important to follow the recommended dosage. The dosage may vary depending on the specific application and the characteristics of the substrate material. In general, for polymer applications, a dosage of 0.1% - 0.5% by weight is usually sufficient. For rubber products, the dosage can range from 0.5% - 2% depending on the type of rubber and the expected service conditions.
Antioxidant 702 can be added during the manufacturing process. For polymers, it can be mixed with the polymer resin before extrusion or molding. In the rubber industry, it can be incorporated during the mixing stage of rubber compounding. In lubricant production, it can be added to the base oil and then thoroughly mixed.
It is crucial to ensure uniform distribution of the antioxidant in the material. This can be achieved through appropriate mixing equipment and processes. Adequate mixing time and intensity are required to ensure that the antioxidant is evenly dispersed, maximizing its antioxidant effect.
A plastics manufacturing company was facing the problem of yellowing and brittleness in their polypropylene products after long - term storage. They added 0.3% of Antioxidant 702 to their polypropylene resin during the extrusion process. After a year of storage, the products showed no signs of yellowing, and their mechanical properties remained stable. The tensile strength and elongation at break of the products with Antioxidant 702 were significantly higher than those without it.
A tire manufacturer was experiencing premature cracking in their tires, especially in high - temperature environments. They added 1% of Antioxidant 702 to their rubber compound. After road tests, the tires showed a 30% increase in the resistance to cracking, and the overall lifespan of the tires was extended by about 20%.
An industrial lubricant producer was dealing with the formation of sludge in their lubricants, which was causing clogging in the machinery. They added 0.2% of Antioxidant 702 to their base oil. After continuous use in industrial equipment for six months, the amount of sludge formation was reduced by more than 50%, and the equipment ran more smoothly with fewer breakdowns.
