Product Features & Applications
Key Features
|
Low molecular weight HALS delivering high light-stabilizing performance, especially in PP thick sections and surface protection |
Broad polymer compatibility — easily dispersed; effective across most commercial polymer systems |
|
Synergistic with antioxidants and UV absorbers — can also be blended with other HALS (e.g., LS-622, LS-944) for enhanced performance |
Light stability independent of polymer wall thickness — effective in both thick sections and PP films / tapes |
|
Low volatility and high thermal stability — stable during high-temperature melt processing |
Excellent hydrolytic stability and migration resistance; suitable for crosslinked polyethylene and olefin copolymers |
Applications
LS-770 is recommended for use in polypropylene (PP), impact-modified PP (TPO), EPDM, polystyrene (PS / HIPS), ABS, SAN, ASA, polyurethanes (PU), polyamides (PA) and polyacetals (POM). Also suitable for crosslinked polyethylene (XLPE) and olefin copolymers (EVA). Best used in combination with antioxidants and UV absorbers; can be combined with other HALS (e.g., LS-622) for synergistic blends. Particularly recommended for thick-section articles requiring high surface protection.
