Perfectly Spherical, Fine Particles of Silica（KE-W）

球形硅微粒子KE是平均粒径控制在0.1-2.5μm的范围内，且粒度分布窄的球形硅微粒子。 球形硅微粒子KE拥有乙二醇分散体型（KE-E）、水分散体型（KE-W）、粉体型（KE-P）、高纯度粉体型（KE-S）4种类型。此外，也可根据您的需求提供对S型进行了表面处理的各种官能团赋予型。 主要用途 树脂填充剂、防粘连剂、液晶密封剂用填料。 优点特性 1.球形，窄粒度分布。 2.可将粒径控制在0.1-2.5μm范围内的任何值。 3.杂质少，纯度高。 4.非晶体。 5.二次絮凝物少，作为一次粒子存在。 性状 球形硅微粒子单分散在水中的乳白色均匀浆料。 Perfectly Spherical, Fine Particles of Silica KE are spherical fine particles of silica with an average particle diameter that is controlled in the 0.1 – 2.5 μm range, and a sharp particle size distribution. Nippon Shokubai offers four types of SEAHOSTAR™ KE: EG (ethylene glycol) dispersion (KE-E), Water dispersion (KE-W), Powder (KE-P), and High purity powder (KE-S). We can also provide KE-S as a surface-treated and various functional groups-imparting type to meet the user’s requirements and preferences. Main Applications Resin fillers, Anti-blocking agents, Fillers for liquid crystal sealing agents. Features and Properties 1.Fine sharp particle and narrow particle size distribution 2.Particle size adjustable from 0.1 – 2.5μm 3.High purity 4.Non-crystalline 5.Exist as primary particles with few secondary aggregates Features Spherical fine particles of silica are monodispersed in water to form a milky white, homogenous slurry.
