Gray White Hollow Glass Microsphere
Gray white HGMs are made from combination of SiO2 and Al2O3 calcined by heat temperature of 1400℃ and sorted.The diameter is between 5-1000 micron.The larger diameters are,the higher the rates of the hollowness,whereas the lower.Outward appearance is gray white.They are a kind of looser powder materials of good fluidity. Their characteristics show as follows:properties of sound-proofing,inflaming retarding and electrical insulating are excellent.The density and oil absorption rate are lower,but the strength is higher.They are widely applied in printing ink,adhesive,engineering plastic,modification rubber and electrical insulating components.The products are widely used due to their stable property,good weather-resistance and low prices.
