Uso do UV-3638<\/h2>\n

1. O UV-3638 \u00e9 um absorvedor de UV eficiente: tem uma absor\u00e7\u00e3o de UV muito ampla, resist\u00eancia ao processamento em alta temperatura, resist\u00eancia \u00e0 alta press\u00e3o, resist\u00eancia a \u00e1cidos e \u00e1lcalis, sem decomposi\u00e7\u00e3o, sem precipita\u00e7\u00e3o, sem migra\u00e7\u00e3o e sem altera\u00e7\u00e3o de odor. Volatilidade muito baixa, forte efici\u00eancia de absor\u00e7\u00e3o, v\u00e1rias vezes maior do que a absor\u00e7\u00e3o de UV comum, nenhum efeito sobre a cor do substrato, boa compatibilidade com a resina, n\u00e3o est\u00e1 envolvido na rea\u00e7\u00e3o do processo de polimeriza\u00e7\u00e3o. Especialmente para pet e pc, tem excelente estabilidade. Usado principalmente em fibras pet; filmes pet; fatias de garrafas pet, para proteger o conte\u00fado das garrafas pet contra danos causados pelos raios UV.<\/p>\n

2. Absorvedor de UV O UV-3638 \u00e9 um absorvedor de UV de benzoxazinona capaz de absorver 200-400 nm de luz UV. A faixa de absor\u00e7\u00e3o abrange UVA, UVB e UVC com um pico de absor\u00e7\u00e3o de 350 nm. A efici\u00eancia de absor\u00e7\u00e3o \u00e9 v\u00e1rias vezes maior do que a dos absorvedores de UV comumente usados, com uma temperatura de perda de calor de at\u00e9 371 graus Celsius. Possui resist\u00eancia a altas temperaturas, resist\u00eancia \u00e0 extra\u00e7\u00e3o, baixa volatilidade, baixa migra\u00e7\u00e3o, ampla faixa de absor\u00e7\u00e3o e alta efici\u00eancia de absor\u00e7\u00e3o, al\u00e9m de retardar o amarelamento da cor e bloquear a perda f\u00edsica. \u00c9 adequado para PET, PBT, PAR, PES, PSU, PPO, PPS, PC, PA sob processamento de alta temperatura, especialmente para filme, folha e placa de PET transparente, filme, folha e placa de PC transparente, filme \u00f3ptico, lente \u00f3ptica, placa de difus\u00e3o de luz. A dosagem geral \u00e9 de 0,1-0,5%.<\/p>\n
