It's a highly effective antioxidant for a variety of elastomers including polybutadiene (BR), polyisoprene (IR), emulsion styrene butadiene (SBR), nitrile rubber (NBR), carboxylated SBR Latex (XSBR), and styrenic block copolymers such as SBS and SIS. Eunox AO-565 is also used in adhesives (hot melt, solvent-based), natural and synthetic tackifier resins, EPDM, ABS, impact polystyrene, polyamides, and polyolefins. Eunox AO-565 is highly effective at low concentrations, matching the performance of other stabilizers at higher levels. It is non-staining and due to its low volatility, it's not lost during polymer processing, drying or storage. Eunox AO-565 can be used in a wide variety of applications. In unsaturated elastomers, it prevents gel formation, maintains excellent polymer color, and prevents changes to molecular weight (e.g. Mooney viscosity). The dosage levels of Eunox AO-565 vary by polymer and range from 0.05% to 0.5%. Extensive performance data is available in many of the substrates mentioned above. The relatively low melting point allows easy dispersion in elastomeric substrates by commonly used melt compounding techniques or it can be incorporated into process streams by dissolving in suitable organic solvents or aromatic extender oils.
