Glass sand for jetting has the features of chemical stability, high mechanical intensity and hardness. They can be jetted onto the object surface with compressed air and can be used on compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls would help reduce elasticity of the surface materials and increase wearing capacity. Diameter (um):50-850
hardness:6-7
Round Rate: ≥80%
SiO2＞65%
