MICRO GLASS BEADS

The micro glass bead is a kind of super-light filling material, which is hollow and sealed. It has the advantages of a large lightweight, low thermal conductivity, dispersivity, fluidity, and good stability. In addition, it has excellent properties such as insulation, self-lubrication, sound insulation and insulation, nonwater absorption, corrosion resistance, radiation protection, non-toxic, and so on. Thermosetting and thermoplastic resin products, this product can be filled in the vast majority of types, the following properties can be improved or determined by the material density (decrease), fluidity, viscosity, rheological properties (reduced) (thickening, sagging), matte effect, shrinkage (decrease), mechanical processing (improve), impact strength, hardness, insulation, explosive properties, acoustic properties, and thermal insulation properties.
