1) Product Introduction
Glass bead for sandblasting has the features of chemical stability, high mechanical intensity and hardness. They can be blasted 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. 
2)  Product Specification:
Main products specification for sandblasting according to following table:

No.	Diameter(μm)	Corresponding sieve size
1	710-425	25-40
2	425-250	40-60
3	250-150	60-100
4	150-100	100-150
5	100-75	150-180
6	75-50	<180

You can choose different size glass bead between 50μm-850μm according to different function.
