Claims12
An abrasive article comprised of abrasive particles, lubricant and polymeric reaction product of components comprising saturated polyol, saturated polyisocyanate, and a free radical source, said abrasive article having a void volume of at least 25 percent, a density in the range of from 0.1 g/cm3 to 1.2 g/cm3 and a Show A durometer in the range of from 10 to 50.
A method for making an abrasive article comprising:
- combining components comprising saturated polyol, saturated polyisocyanate, a free radical source, a lubricant, and abrasive grains to provide a curable composition;
- and
- curing the curable composition to provide an abrasive article having a void volume of at least 25 percent, a density in the range of from 0.1 g/cm3 to 1.2 g/cm3 and a Shore A durometer hardness in the range of from 10 to 50.
