High-precision microparticles known as "High Presica" have the characteristics of "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 uniform thickness in the cells containing liquid crystal materials, 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, etc.), and particles for high-performance film coatings. *For more details, please download the catalog.*

basic information
【Features】 - The particle size is very uniform, capable of ranging from 0.2μm to 70μm. - It contains almost no impurities, with the content of radioactive elements such as uranium and thorium being extremely low at below 0.1ppb, indicating very high purity. It is also optimal as a gap spacer for liquid crystal displays, which dislike the elution of alkaline ions, and as a filler for semiconductor encapsulants, which 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 via surface silanol groups. - It is thermally very stable, showing 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.
