MX Abrasives

In general Cratex MX abrasives are more aggressive than Cratex rubber bonded abrasives. The real difference between the two is the metal removal capabilities.

Unlike Cratex Rubberized Abrasives Cratex MX is a laminate bond. The MX manufacturing process is similar to that of coated abrasives (sandpaper). MX is made from cloth material sheets coated with either a latex or resin adhesive. The sheets are then coated with abrasive and stacked to reach a predetermined thickness. The stack of sheets are then cold pressed to form a large slab. The slab is oven cured. After curing the slab is sliced and dice to produce either type 1 wheels or mounted wheels.

Since a laminate bond is pressed or compressed to form a slab utilizing an adhesive the MX material is much firmer than a rubber bond, the result us that the MX bonds holds the abrasive grains until they are won. Rubber bonds being resilient the abrasive grains push back into the rubber matrix during use. The rubber is worn away and the abrasive falls out.


Cratex MX is available in two different bonds and four grades.

Latex Bond:

  • CXG = (soft bond) general purpose
  • CXH = (medium bond) semi-aggressive

Resin Bond:

  • CXI = (hard bond) aggressive
  • CXN = (extra bond) very aggressive
