Applications

• RIANOX® 565 is 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. RIANOX® 565 is also used in adhesives (hot melt, solvent-based), natural and synthetic tackifier resins, EPDM, ABS, impact polystyrene, polyamides, and polyolefins.
• RIANOX® 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, RIANOX® 565 is not lost during polymer processing, drying or storage. RIANOX® 565 can be used in a wide variety of applications. In unsaturated elastomers, RIANOX® 565 prevents gel formation, maintains excellent polymer color, and prevents changes to molecular weight.
