Glass beads are made of broken glass, flat glass and other raw materials by high temperature melting bead processing. Low thermal conductivity, high strength, good chemical stability, and the texture of glass beads themselves, glass beads instead of plastic raw materials are widely used in filling, such as gravity blanket filling, compression filling, medical filling, weighted blanket filling, toy filling and so on.
