Description

Spherical silica

Product Introduction

Our company utilizes a chemical process technology route for the mass production of spherical silica (SiO₂) micropowder (referred to as spherical silica micropowder). The product’s spheroidization rate, true sphericity, melting rate, and high purity indices meet or exceed those of similar products.

Using spherical silica micropowder as a filler can significantly enhance the rigidity, wear resistance, weather resistance, impact resistance, compressive strength, tensile strength, flame resistance, excellent arc insulation properties, and UV radiation resistance of the products.

Given these characteristics, spherical silica micropowder can be widely applied in large-scale and ultra-large-scale integrated circuit packaging and electronic components, insulation casting of high-voltage electrical devices; it can also be used in advanced rubber tires, silicone rubber, silicon-based substrate materials, high-grade inks, coatings, sealants, adhesives, electronic ceramics, optical quartz glass, enhanced modified engineering plastics, functional plastic films, optical fiber drawing, medical dental materials, cosmetics, and numerous other fields such as chemical medicine and environmental protection. Spherical silica micropowder has become one of the most important and critical basic materials in many high-tech fields.

Characteristics

  1. High purity, with SiO₂ content reaching over 99%
  2. High whiteness, resistant to yellowing
  3. High acid and alkali resistance
  4. High covering power, good gloss, uniform and smooth
  5. Excellent dispersibility, low oil absorption
  6. Uniform particle size distribution
