Injection molded abrasive article and process

An abrasive article comprising:

• an abrasive body produced from a homogeneous composition comprising:
• from about 1% to about 20% by volume primary abrasive grit selected from the groups consisting of diamond grit, tungsten carbide grit, silicon carbide, aluminum oxide, garnet, cubic boron nitride, and mixtures thereof;
• from about 5% to about 80% by volume secondary fillers;
• and
• from about 5% to about 90% by volume of a thermoformable polymer selected from the group consisting of thermoplastic polymers having a softening point temperature greater than about 100.degree. C. and less than about 400.degree. C. and thermoset polymers.

A process of manufacture of an abrasive article comprising the steps of:

• a) providing an injection mold, extrusion or blow molding apparatus for forming a shaped abrasive article;
• b) formulating a mixture, said mixture comprising from about 1 to about 20% by volume primary abrasive grit, from about 5 to about 80% by volume secondary fillers and from about 5 to about 90% of an injection moldable or blow moldable thermoformable polymer, selected from the group consisting of thermoplastic polymers having a softening point temperature greater than about 100.degree. C. and less than about 400.degree. C. and thermoset polymers;
• and
• c) molding the mixture in said injection molding, extrusion or blow molding apparatus.
