The product, High Quality antioxidant 697 cas 70331 - 94 - 1 With Low Price, is a highly efficient antioxidant. The CAS number 70331 - 94 - 1 uniquely identifies this chemical compound in the global chemical registry. This antioxidant is known for its high - quality characteristics and cost - effectiveness, making it an ideal choice for various industries.
It has excellent thermal stability, which allows it to maintain its antioxidant properties even under high - temperature conditions. The molecular structure of antioxidant 697 provides strong free - radical scavenging ability, effectively preventing the oxidation of organic materials.
Antioxidant 697 has a wide range of applications across multiple industries. In the polymer industry, it is used to prevent the oxidation of plastics, rubber, and fibers. By adding antioxidant 697, the service life of these polymer materials can be significantly extended. For example, in the production of polyethylene and polypropylene plastics, it helps to resist yellowing, embrittlement, and loss of mechanical properties caused by oxidation.
In the lubricant industry, antioxidant 697 is added to lubricating oils to inhibit the oxidation of oil components. This reduces the formation of sludge and varnish, improving the lubrication performance and reducing wear of mechanical parts. It is also used in the food industry as an antioxidant for edible oils and fats, preventing the rancidity of oils and maintaining the freshness and quality of food products.
The usage of antioxidant 697 depends on the specific application and the type of material it is added to. In the polymer industry, the typical addition level ranges from 0.1% to 1% by weight. Before adding, it is recommended to pre - mix antioxidant 697 with other additives to ensure uniform dispersion. During the plastic extrusion or injection - molding process, it should be added at the appropriate stage to achieve the best antioxidant effect.
In the lubricant industry, the addition amount is usually between 0.5% and 2% by weight. It should be added during the oil blending process under appropriate temperature and stirring conditions to ensure full dissolution and dispersion. In the food industry, the usage must comply with relevant food safety regulations, and the addition level is strictly controlled according to the specific food product.
Case 1: A plastic manufacturing company used antioxidant 697 in the production of polyethylene pipes. Before using antioxidant 697, the pipes would start to show signs of oxidation and yellowing after being exposed to sunlight and oxygen for about 6 months. After adding 0.5% antioxidant 697 by weight, the pipes showed no obvious oxidation or yellowing even after 2 years of outdoor exposure, significantly improving the product's quality and market competitiveness.
Case 2: A lubricant manufacturer added antioxidant 697 to a high - performance engine oil. In bench tests, the oil without antioxidant 697 showed a significant increase in acid number and sludge formation after 200 hours of operation. In contrast, the oil with 1% antioxidant 697 by weight maintained a stable acid number and had minimal sludge formation even after 500 hours of operation, indicating excellent oxidation resistance.
