Applications
1. Road marking glass beads Can be divided into dropping on type and mixing type； Using for roading and to raise the safety of night driving by it’s reflective performance. Dropping on glass beads can be directly dropping on the road marks； Mixing glass beads need to use together ；
2.Sandblasting glass beads Mainly using for the surface sandblasting and shot blasting of metals,glass,rubber and plastics,acrylic,and can avoid the workpieces be damaged.
3. Filling/Grinding glass beads Mainly using as filling media of weighted-blanket,plush toys,eyeshade,medical package, uniform filled and good textures Meanwhile can be used as grinding media for paint,oil,coating,pigment,etc.
4. Precise glass beads High precision and roundness，can be used as media for chemical ink,wine bottle cap,water pum valve,cosmetics valve,machinery bearings
