- Features & Benefits
PUREstab 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 is not lost during polymer processing, drying or storage. It can be used in a wide variety of applications. In unsaturated elastomers, PUREstab 565 prevents gel formation, maintains excellent polymer color, and prevents changes to molecular weight.
Applications & Uses
- Compatible Polymers & Resins
- Applications
PUREstab 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. PUREstab 565 is also used in adhesives (hot melt, solvent-based), natural and synthetic tackifier resins, EPDM, ABS, high impact polystyrene, polyamides, and polyolefins.
The use levels of PUREstab 565 vary by polymer and range from 0.05% to 0.5%. The relatively low melting point allows easy dispersion in elastomeric substrates by commonly used melt com-pounding techniques or it can be incorporated into process streams by dissolving in suitable organic solvents or aromatic extender oils.
