Abrasive Materials

Olstral proposes a wide and efficient range of abrasive materials made of canvas and paper or abrasive discs for any grinding, polishing, cutting, deburring, etc. in order to increase quality and reduce production costs.

  • The abrasive type products are obtained by depositing abrasive granules on different supports such as paper, cloth, combination, and fixing them with binders (glue or resins).
  • The products resulting from this manufacturing process are then converted into different formats for use in certain stages of the processing of materials, on various specific machines, or manually.
  • The abrasive bodies are shaped, made of hard crystals with a large number of cutting edges. These crystals are bonded together with binders, forming products of various shapes and sizes.
  • The abrasives on the support are products made up of three main elements – a flexible or semi rigid support, abrasive grains and an adhesive that adheres to the support granules.
  • There are a wide range of abrasives on the support in various formats and sizes: wide and narrow endless bands, with sinuous edges, rolls, rolled slots with parallel or offset slots, plane, perforated or non-perforated discs, self- perforated or non-perforated flat velcro disks, rectangular, hydro-resistive and varnished rectangular sheets, lamellar brush-type blades, spliced, helical and lamellar-fronted, abrasive with one face, two faces, four abrasive faces.
  • Granule type: normal electrocorindone, semi-zinc / zirconium electrocorindone, black silicon carbide.
  • These products ensure a good surface quality and an optimal performance in the grinding operations of wood, metal, glass, porcelain, lacquer and paints, leather, etc.
