What is the Stuffing beads in toys weighted blanket?
Stuffing beads are also called micro glass beads, 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, stuffing beads instead of plastic raw materials are widely used in the filling, such as gravity blanket filling, compression filling, medical filling, weighted blanket filling, toy filling and so on.
The main size is 06-0.8mm, 08-1.2mm, 1-1.5mm, 1-2-3-4-5-6mm. For more details: pls contact Email: cindyhu@hnsicheng.cn
