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