De chemische naam is\u00a0<strong>2-Hydroxy-4-n-octoxybenzofenon<\/strong>, behorend tot de\u00a0<strong>klasse benzofenonen van UV-absorbers<\/strong>. Hieronder staan de gedetailleerde functies en toepassingen:<\/p>\n<hr \/>\n<h3><strong>Aanbevelingen voor gebruik<\/strong><\/h3>\n<ol start=\"1\">\n<li><strong>Dosering<\/strong>:\n<ul>\n<li>Een typische dosering is\u00a0<strong>0,1% tot 0,5%<\/strong>\u00a0van het polymeergewicht, afhankelijk van de toepassing en het materiaaltype.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Verwerkingstemperatuur<\/strong>:\n<ul>\n<li>Geschikt voor conventionele verwerkingstemperaturen, maar mag de thermische ontbindingstemperatuur niet overschrijden (meestal boven 250\u00b0C).<\/li>\n<\/ul>\n<\/li>\n<li><strong>Combinatie met andere additieven<\/strong>:\n<ul>\n<li>Kan worden gebruikt met lichtstabilisatoren (bijv.
