1. Este produto \u00e9 um absorvedor de ultravioleta de alta efici\u00eancia, que pode absorver com efic\u00e1cia a luz ultravioleta com comprimento de onda de 270 a 340 nan\u00f4metros.
\n2. O desempenho da estabiliza\u00e7\u00e3o da luz \u00e9 semelhante ao do UV-326 e do UV-327, mas esse produto tem boa compatibilidade com a resina, baixa volatiliza\u00e7\u00e3o t\u00e9rmica e alta resist\u00eancia \u00e0 lavagem.
\n3. Usado principalmente para poliolefina (especialmente polietileno), poli\u00e9ster, pol\u00edmero estir\u00eanico, poliamida, polimetilmetacrilato, policarbonato, elast\u00f4mero e outros pol\u00edmeros.<\/p>\n
