Application\uff1a<\/strong><\/p>\n

1. Ce produit est un absorbeur d'ultraviolets \u00e0 haut rendement, qui peut absorber efficacement la lumi\u00e8re ultraviolette d'une longueur d'onde de 270 \u00e0 340 nanom\u00e8tres.
\n2. Les performances de stabilisation de la lumi\u00e8re sont similaires \u00e0 celles de l'UV-326 et de l'UV-327, mais ce produit pr\u00e9sente une bonne compatibilit\u00e9 avec la r\u00e9sine, une faible volatilisation thermique et une grande r\u00e9sistance au lavage.
\n3. Principalement utilis\u00e9 pour la polyol\u00e9fine (en particulier le poly\u00e9thyl\u00e8ne), le polyester, le polym\u00e8re styr\u00e9nique, le polyamide, le polym\u00e9thacrylate de m\u00e9thyle, le polycarbonate, l'\u00e9lastom\u00e8re et d'autres polym\u00e8res.<\/p>\n
