Cratex is a manufacturer of specialized abrasives products used primarily for metal, glass and lapidary conditioning and finishing. Cratex has been in the business of manufacturing rubberized abrasives for approximately seventy years. These products have abrasive grain mixed homogeneously throughout the rubber so that as the product wears down, sharp, new grains are constantly being exposed. This allows the products to perform the same from start to finish.

Grit Textures

Each Cratex size and shape is made in four standard Grit Textures or compositions which differ in accordance with the mesh size of the abrasive grain used. [C] COARSE (Green) [M] MEDIUM (Dark Brown) [F] FINE (Reddish Brown) [XF] EXTRA FINE (Grey Green)

Cratex Standard Bond

The Cratex bond common to each of the four Grit Textures is made with premium grade oil-resistant chemical rubber. In contrast to conventional grinding wheels the Cratex bond has unique cushioned action...cuts freely, smoothly and softly without gouging or digging into the work surface. It resists clogging or smearing, and is ideal for a broad range of applications where metallic or non-metallic surfaces must be smoothed and polished without loss of dimensional tolerances or control.

Cratex Abrasive Type

The abrasive type used in Cratex Rubberized Abrasives is premium-quality Silicon Carbide that has been washed, dried and treated to remove impurities and then carefully screened to U.S. Department of Commerce standards for size. Although silicon carbide is more expensive than other abrasive materials, it is used because it has a high level of purity and has been found to be best for the broadest range of light deburring, smoothing, cleaning and polishing applications on ferrous and non-ferrous alloys as well as many non-metallics, such as glass.
