Antioxidant 565 CAS NO.991-84-4
Antioxidant 565, with CAS number 991-84-4, is a hindered amine light stabilizer (HALS) and triazine derivative, chemically named 2,6-di-tert-butyl-4-(4,6-bis(octylthio)-1,3,5-triazin-2-ylamino)phenol. It is primarily used as a rubber antioxidant and polymer stabilizer, offering dual protection against heat aging and UV degradation. The compound’s structure combines steric hindrance with light-absorbing triazine groups, making it effective in outdoor applications.
This HALS antioxidant is compatible with a broad selection of polymers, including polyolefins, elastomers, and industrial coatings. Its high molecular weight (typically 685.0 g/mol) and low volatility ensure long-term stability in demanding environments. Typical HALS stabilizers in this class exhibit melting points above 100°C and are supplied as fine powders or granules for easy incorporation into compounding processes.
Industries such as plastics manufacturing, rubber production, and automotive components use Antioxidant 565 to enhance the durability of their products. The additive is particularly valuable in applications exposed to sunlight or high temperatures, where it prevents cracking, discoloration, and loss of mechanical properties. Importers should confirm HS classification (3812.39 for rubber antioxidants) and packaging details, as the product is often shipped in 20 kg or 25 kg containers.
