道康宁PC光扩散剂EP2720

PC光扩散剂-EP2720外观是一种白色流动性的粉末（实为直径很微小的有机微珠）,加入不同材质的树脂中，会以一种细微的透明玻璃球体均匀的分散在基体中，通过与不同基材的折射率的差异，光源穿透式的进行折射，改变光的行进路线，达到匀光而又透光的目的。同时满足雾度值和透光率的需求。       当应用在PC光扩散板中或PC灯罩中,PS面板等添加0.5%-1%光扩散剂在透明PC中起到明显的扩散效果，可以遮盖住点光源达到柔和视角效果，又能保持较高的透光率，透光率一般能达到85%以上。EP2720在PMMA中的应用，提高雾度效果的同时，仍旧保持了原有的透光性，也可以作为一种磨砂剂使用，使产品即具有光滑表面的同时又起到磨砂的视觉效果。3.产品描述<table border= "1 " cellpadding= "0 " cellspacing= "0 " style= "width: 462px; "><tr><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "214 ">主要成分</td><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "240 ">有机类聚合物</td></tr><tr><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "214 ">外观形状</td><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "240 ">白色细小微珠</td></tr><tr><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "214 ">折光率</td><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "240 ">1.49</td></tr><tr><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "214 ">耐热温度</td><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "240 ">250-270摄氏度</td></tr><tr><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "214 ">游离率</td><td style= "border-right: medium none; border-top: medium none; border-left: medium none; border-bottom: #cc6633 1pt solid; " valign= "top " width= "240 "><1.0%</td></tr></table>
