Our sponge sand uses special sponge as the substrate. Made from high-quality brown corundum or silicon carbide through special treatment and special adhesive formula.


Sponge sand blocks are generally divided into three particle sizes: coarse, medium, and fine.


60 # -240 #, belonging to the coarse sand category, are generally products with hard and rough grinding, such as metal, jade, wood, walls, etc.


240 # -400 #, belonging to the medium sand grade, is commonly used for secondary polishing of rough grinding. For some parts with low polishing requirements, they can be directly formed, such as walls.


600 # -2000 #, belonging to the fine range, is suitable for the fine polishing of workpieces such as mahogany furniture, amber, bodhi, gold, etc.
