Industrial-Grade Spherical Silica Micro-Powder with Uniform Particle Size
Share to:
Industrial-grade spherical silica micro-powder with uniform particle size is a high-purity silicon dioxide (SiO2) powder material. Spherical particles are formed through special processing techniques, featuring uniform particle size distribution, good fluidity, and low specific surface area. Its unique spherical structure can significantly enhance the filling property, dispersibility, and mechanical properties of materials, and it is widely applied in fields such as electronic packaging, polymer composite materials, coatings, adhesives, ceramics, and aerospace. Through strict quality control, the product ensures low impurity content and high chemical stability, meeting the requirements of harsh industrial scenarios such as high temperature, high frequency, and high insulation.
