High-precision microspheres, known as High Presica, have characteristics such as "uniform particle size," "spherical shape," "high purity," and "adjustable hardness."
High Presica is a microparticle synthesized from high-purity silicon compounds. There are hard silica particles that excel in load resistance and soft organic-inorganic hybrid particles that do not scratch delicate substrates. The characteristics of High Presica include a very uniform particle size (monodisperse), a nearly spherical shape, and extremely high purity. Leveraging these features, it is used as a spacer in liquid crystal displays (LCDs) to maintain a uniform thickness of the cell containing the liquid crystal material, making it an essential component for enhancing LCD resolution. Additionally, it is used in various fields such as spacers for adjusting adhesive layer thickness, high-performance resin fillers (for semiconductor encapsulation materials, among others), and particles for high-performance film coatings. *For more details, please download the catalog.*

basic information
【Features】 - The particle size is very uniform, with a range from 0.2μm to 70μm. - It contains almost no impurities, with the content of radioactive elements such as uranium and thorium being below 0.1ppb, making it extremely high purity. It is also ideal as a gap spacer for liquid crystal displays that dislike the elution of alkaline ions, and as a filler for semiconductor encapsulants that are sensitive to soft errors. - Surface treatment with silane-based or titanate-based coupling agents is possible to impart functionality. Additionally, it can serve as a carrier for composite particle synthesis, allowing functional molecules to be bonded through surface silanol groups. - It is thermally very stable, with almost no weight change in the temperature range of 200°C to 500°C. * We are conducting research and development towards new functionalities and high value-added particles, such as larger particle sizes, particles with controllable refractive indices, porous particles, and hollow particles. * For more details, please contact Ube Eximo.
