grinding glass bead

Grinding glass bead (filler material and color bead) They are mainly used for the disperser, grinding media of industries, such as coloring, paint, ink, coatings, resins, chemical engineering, with the advantages of smooth surface, even size, high hardness, good chemical stability. Thanks to the characteristics of heat-resistant, wearable, compression strength, the filling-type bead could be used to improve glass fibre reinforced plastic, rubber, and so on Appearance Round,Clean,Transparent , no sensible air bubble and impurity Specific gravity 2.4-2.6g/cm3 Roundness ＞80% Refraction index ≥1.5 SiO2 ＞62% Mosh Hardeness 6-7 Micro hardness 630kg/mm2
