Filled glass beads
Filled glass beads are divided into solid glass beads and hollow glass beads. Glass beads are small spheres with high ball shape ratio, ball bearing effect and very good fluidity. Filling in coatings and resins can improve the fluidity of materials, reduce viscosity, make materials easy to level, increase external hardness and toughness, and improve product quality. Hollow glass beads have the characteristics of high resistivity, low thermal conductivity and small thermal shrinkage. They have a good weight reduction and sound insulation effect, so that the products have better crack resistance and reprocessing performance.
Filled glass beads have low thermal conductivity, high strength, good chemical stability and excellent fluidity. They are widely used in industry, transportation, aviation, medical devices, nylon, rubber, engineering plastics and other fields as fillers and enhancers. Such as gravity blanket filling, compressive filling, medical filling, toy filling, joint sealant, etc. Common particle sizes of glass beads for filling: 0.3-0.6mm, 0.6-0.8mm, 0.8-1.2mm, 1-1.5mm, etc.
