Abrasive sanding discs consist of abrasive grains
applied to a backing made of cloth, fiber, film, paper, non-woven,
or other material. The abrasive grains remove surface materials
such as metal, ceramics, glass, plastics, and paint. Consequently,
abrasive discs are used in wet and dry grinding, sanding, cleaning,
polishing, and surface preparation in a variety of industries,
including metalworking, woodworking, ceramics, and semiconductors.
A disc’s backing, abrasive grain, grit size, and mounting
help determine its applications.
Sanding discs include paper discs on a roll for automative finishing, bodywork and many general purpose applications. These discs are paper with pressure sensitive adhesives. Discs are typically 5" x 6" wide.
Sanding discs are hook and loop and pressure sensitive adhesive. These discs are paper and micron film. Applications include countertop finishing, automotive finishing and most general purpose applications.
Nonwoven sanding discs are used for metal finishing. Typically used in air tools and grinders, most applications are metalworking for small, hard to get into areas and curved materials.
Resin fibre discs and flap discs have vulcanized
rubber backing for durability and high speed grinding. Grinding
minerals include aluminum oxide, zirconia, and ceramic grain. Applications
are typical grinding welds and metalworking.
