Application details
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 blasting media
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.
