Poly Strip Discs are manufactured from polyfibre and impregnated with coarse grain silicon carbide. After that, they are strengthened with synthetic resin. This combination results in an abrasive material with an open structure. It is sharp and flexible and doesn’t clog with shavings, so that you can continue sanding without any problems. This makes the Clean & Strip Disc the ideal abrasive material for effectively cleaning a surface. Because of its unique open structure, the Clean & Strip only removes the upper layer of the object, without grinding or cutting into the surface. This open structure enables cool grinding.
