Choose From Our Large Inventory of sia Abrasives Products

National Abrasives, Inc. is your one-stop resource for sia Abrasives products in the following categories:

  • Coated Abrasives: As one of the world’s leading producers of coated abrasives, sia can provide a versatile abrasive solution that meets your company’s unique requirements. sia coated abrasives are the result of painstaking research and development, combined with an unwavering passion for quality, precision and perfection. sia coated abrasive options include flexible backed abrasives for everything from surface preparation to finishing of a wide variety of materials. You will find the perfect product for delivering superior wet sanding results, high-speed sanding applications and more.
  • Nonwoven Abrasives: Nonwoven abrasives offer a number of important advantages over traditional abrasive materials including the ability to adapt to contours, more even grit distribution throughout the material, reduced susceptibility to clogging and the flexibility to use wet, dry, or with various grinding fluids. sia nonwoven abrasive products include 3-dimensional sanding products featuring nonwoven abrasives, as well as 2-dimensional products with scm abrasives. Both offer the same basic structure; the primary difference lies in the fiber strength and the type of application. All products include high-performance fiber coatings that maximize sanding results.
  • Foam Abrasives: Foam abrasives offer an ideal solution for removing materials on profiled surfaces and hard-to-reach areas. Sanding with foam abrasives also ensures a smooth, even finish that is essential for surface preparation for painting and varnishing. Foam abrasives enable a three-dimensional pressure application that provides the perfect finish with low scratch depth, so the abrasive grit will not cut into the surface as deeply and is less likely to break off during sanding, while also resulting in less material removal. In short, foam abrasives offer the advantages of maximum conformability and optimal pressure equalization for superior sanding results.
  • Bonded Abrasives: sia bonded abrasives are manufactured to the highest quality and performance standards. The exact abrasive performance will depend on the individual product specifications. Abrasive discs are available in various grit types including aluminum oxide, silicon carbide and a combination of aluminum oxide and zirconia alumina. Grit size options range from 16 (very coarse) to 100 (very fine). You can also select from a number of disc formats including straight cutting, depressed-center cutting, depressed-center grinding and semi-flexible grinding. Multiple disc dimensions are also available.
