What are the advantages of sponge sand
Sponge sand is foam plastic as the base material, with good elasticity and deformation, do not scratch the workpiece, according to the shape of the workpiece changes, after washing with sponge sand. Widely used in various irregular and complex processing of cotton grinding, wood, metal, plastic, paint and other materials for the special surface of the manual grinding, household and kitchen cleaning supplies.

Sponge sand block is made of foam sponge covered with alumina, chemical adhesive, soft and durable. It can polish, arc or carve concave and convex lines on the surface of metal and wood products with irregular shape, suitable for the surface of metal and wood products without deformation. In addition, sponge sand is a highly elastic sponge as the carrier, viscose coated abrasive, abrasive grain size of 80-400.
Sponge sand block with high density, good flexibility, high toughness, good self-grinding, low consumption of sand, recyclable, good polishing finish, chemical composition stability, wear resistance, acid and alkali resistance and other characteristics.In the process of continuous grinding and grading, the shell fracture with sharp edge and sharp edge can form a new cutting edge, making its grinding performance better than other abrasives. In particular, sponge polishing sand due to its high hardness, high specific gravity, stable chemical properties and unique self-grinding, has become an effective solution to the CNC polishing process of the first choice, but also an ideal polishing material.
