Special Features

  • 💖1.Ideal spherical structure, ultimate fluidity The high spheroidization rate silica powder obtained through special processing has a smaller specific surface area and higher bulk density compared to irregular angular powder. It exhibits excellent fluidity in resin, significantly reducing the viscosity of the system and meeting the stringent requirements of precision electronic packaging and high-fill composite materials.
  • 💖2. Dual hydrophilic/hydrophobic options available, easy to disperse We offer both hydrophilic (water-loving) and hydrophobic (water-repellent) types. The hydrophilic type is highly dispersible in water-based coatings and adhesives; the hydrophobic type seamlessly integrates into oil-based resins, silicone rubbers, and organic solvent systems, effectively eliminating the problem of agglomeration.
  • 💖3. Precise Control at Micro and Nano Levels From micro levels (1-10 μm) to nano levels (20-100 nm), the particle size distribution is narrow and the dimensions are precise. Micro spheres offer excellent light extinction, anti-adhesion, and filling effects; nano spheres bring magical thickening, thixotropic, and reinforcing functions, enabling you to upgrade your formulations.
  • 💖4. High-purity silicon dioxide, with both whiteness and stability The purity of SiO₂ is ≥ 99.5%. It appears as a pure white and fluffy powder, without any black impurities. Its chemical properties are highly stable, resistant to acids and alkalis, high-temperature resistant, and has excellent insulation properties. The products made from it have a bright color, long-lasting and reliable physical properties, and enhance the value of high-end products.
  • 💖5. Multi-functional filler, covering industries to daily care Widely used in coating gloss reduction and hardness enhancement, silicone rubber reinforcement, electronic potting filling, epoxy resin cost reduction, plastic film opening agent, and skin feel improvement for high-end cosmetics (powder cakes, loose powders). One powder for multiple uses, it is the ideal inorganic filler for you to reduce costs and increase efficiency.

Description

💖This is a spherical silica powder specially designed for high-performance formulations. It has both hydrophilic and hydrophobic surface properties and is further divided into micrometer and nanometer levels. Compared to traditional gas-phase silica or angular silica micro-powders, our spherical silica powder, with its unique spherical morphology, can freely slide within the substrate like miniature balls, significantly reducing the viscosity of the resin system and enabling you to easily achieve high proportion filling.
💖Why choose spherical silica powder?
💖· Hydrophilic type: The surface retains a large amount of silanol groups, suitable for water-based coatings, water-based adhesives, and concrete reinforcement. The particles can be easily wetted by water and will disintegrate after stirring. · Hydrophobic type: After surface hydrophobic treatment, it has excellent compatibility with organic resins, silicone oils, and solvents. A small amount can be quickly dispersed into the ink system, providing a smooth touch, and there will be no "re-coarsening" or hard lumps formation.
💖How to select the particle size?
💖· Micron spheres: They are ideal for use as opacifiers, anti-adhesion agents and rigid fillers. They can provide a fine matte luster to the paint and prevent adhesion of openings in plastic films. · Nanometer spheres: They possess nanoscale effects and can be used as a wear-resistant reinforcing agent for transparent plastics. They can increase the smoothness and extensibility in skin care products and cosmetics, and fill fine wrinkles.
💖Application scenarios: Electronic adhesives / LED potting compound / Silicone rubber compounding rubber / UV varnish gloss reduction / Wood paint and industrial paint / Epoxy floor filler / Plastic film open granules / BJD doll resin filler / Powder cake and honey powder / Special ceramic sintering additives.
💖We strictly use high-purity crystalline silicon raw materials. The powder has a whiteness of over 96% and contains no heavy metals. It is vacuum-sealed and packaged to prevent moisture and clumping, with a long shelf life. Whether for industrial production or laboratory trials, it is a reliable precision powder that you can trust.
