Abralon uses the same abrasive as wet/dry sandpaper: silicon carbide.
Some of the particle in use, Storm and Columbia (Track & AMF) are soft enough, as far as I know, that silicon carbide will abrade them and make them smooth, changing the nature of the ball's surface. That is why I suggested, if this ball is a particle ball, that you should use Scotch-Brite nylon pads to adjust the surface. Its abrasive is hard enough to smooth out the resin base, but not so hard as to change the particle.
