The product, High Quality antioxidant 1010 cas 6683-19-8 With Best Price, is a highly effective antioxidant. Its CAS number is 6683 - 19 - 8. Chemically, it belongs to the hindered phenol antioxidant family. This antioxidant has excellent thermal stability and low volatility. It is a white to off - white crystalline powder. The melting point of this product typically ranges from 110 - 125°C. It has good solubility in common organic solvents such as benzene, toluene, and chloroform, but is insoluble in water. The purity of our High Quality antioxidant 1010 is usually above 99%, ensuring its high - performance in various applications.
High Quality antioxidant 1010 is widely used in the polymer industry. In polyolefins, such as polyethylene (PE) and polypropylene (PP), it can prevent the oxidation of polymers during processing and long - term use. Oxidation can lead to polymer chain scission, cross - linking, and the formation of carbonyl groups, which in turn cause the deterioration of mechanical properties, such as loss of tensile strength and impact resistance. By adding this antioxidant, the service life of polyolefin products can be significantly extended. It is also used in engineering plastics like polyamides, polyesters, and polyurethanes. In these materials, it helps to maintain the color and physical properties, especially when exposed to high temperatures and oxygen. Additionally, it can be used in elastomers, adhesives, and lubricants to protect them from oxidative degradation.
When using High Quality antioxidant 1010, it should be added to the polymer matrix at an appropriate stage of processing. For polyolefins, it can be added during the polymerization process or compounding. The recommended dosage is usually in the range of 0.1% - 1.0% by weight, depending on the specific application requirements, processing conditions, and the expected service life of the final product. For example, in thin - walled polypropylene products that are exposed to sunlight and oxygen for a long time, a higher dosage may be required. It is important to ensure uniform dispersion of the antioxidant in the polymer. This can be achieved through proper mixing techniques, such as using high - speed mixers or twin - screw extruders. Before large - scale production, it is advisable to conduct small - scale trials to determine the optimal dosage and processing parameters.
Case 1: A plastic pipe manufacturing company was using polypropylene to produce water pipes. Without the use of antioxidant 1010, the pipes started to show signs of yellowing and embrittlement after only a few months of outdoor use. After adding 0.5% of High Quality antioxidant 1010 during the compounding process, the pipes maintained their original color and mechanical properties even after two years of continuous exposure to sunlight and water. The company reported a significant reduction in product returns due to quality issues.
Case 2: An automotive parts manufacturer was producing polyurethane foam seats. Oxidation was causing the foam to become brittle and lose its cushioning effect. By incorporating 0.3% of the antioxidant into the polyurethane formulation, the seats showed improved resistance to oxidation. Accelerated aging tests indicated that the foam retained its elasticity and durability for a much longer time, meeting the automotive industry's strict quality standards.
