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

1. Dit product is een ultravioletabsorber met hoog rendement, die effectief ultraviolet licht met een golflengte van 270-340 nanometer kan absorberen.
\n2. De lichtstabilisatieprestaties zijn vergelijkbaar met UV-326 en UV-327, maar dit product heeft een goede compatibiliteit met hars, een lage thermische vervluchtiging en een hoge wasbestendigheid.
\n3. Voornamelijk gebruikt voor polyolefine (vooral polyethyleen), polyester, styreenpolymeer, polyamide, polymethylmethacrylaat, polycarbonaat, elastomeer en andere polymeren.<\/p>\n
