1.	The chemical composition is silicon dioxide, no fear for the interference of chemical activity
2.	True rounded flexible grits, impact-tolerating, several cycles, low loss.
3.	Low wearing for nozzles, extending the life of a nozzle.
4.	Round ball-surfaced, no damage on the processed surface and precision sizes.
5.	After treatment, the surface of the workpiece becomes smooth with peculiar finish process, enhancing product value.
6.	Suitable for dry and wet blasting operations
7.	For the metal tiny crevices, use tiny glass beads in wet blasting for revelation

1.	Bead-crashing of aerospace parts for removing the stress and for increasing fatigue strength and reducing friction and wearing.
2.	Blasting and rust-clearing, paint-clearing, clearing of amassed carbide and of cutting traces of processing
3.	Pre-treatment of positive polarity and electroplating, which, in addition to cleaning, can also increase the area of adhesion.
