Product performance and characteristics:


Silver-coated glass microspheres use electroless plating technology, and after specific molding and surface treatment processes, silver plating layers of different thicknesses are formed on the surface of solid and hollow glass microspheres. It not only has good conductivity of pure silver and other metals, but also has the advantages of low density, low cost, low oil absorption, narrow distribution, and easy dispersion. It is a promising highly conductive filler.
