<p>A composite abrasive filament, including at least one preformed core at least partially coated with a hardened, abrasive-filled thermoplastic elastomer, exhibits increased abrading life over previously known abrasive filaments. Previously known abrasive-filled nylon filaments have limited stiffness and lose their stiffness as temperature approaches 70 °C. The composite abrasive filaments of the present invention are more efficient and more resistant to flex fatigue failure than abrasive-filled nylon filaments. Also disclosed are methods of making such filaments and using such filaments in article form to abrade a variety of workpieces.</p> |
