SiC (Silicon Carbide) is the hardest and sharpest of the minerals used in abrasives. Thanks to its hardness and very sharp shape, this abrasive is ideal for multiple applications that do not require great pressure when cutting. Its grains are friable and, when broken, they continually expose new cutting edges that allow rapid removal of the material. It is more aggressive than Alox but wears out more quickly.

The foam is used to cushion the flexible abrasive, usually with a paper backing. It can have different thicknesses and elasticities.

The type of fabric is always adjusted to the abrasive in question and comes in a wide range of weights and strengths.
