Abrasive belt is a belt of cloth or paper coated with abrasives, used in a variety of processes such as grinding and polishing.

1.According to the classification of substrate, it can be divided into four kinds.

Cloth sand belt: with cloth as the substrate, common cloth materials include natural fibers, synthetic fibers and modified fibers. The cloth sand belt has good tensile strength and flexibility, which is suitable for many metal processing occasions.

Paper base sand belt: With paper as the base material, paper base sand belt has moisture resistance, suitable for occasions with large changes in environmental humidity. At the same time, paper based sand belt is also commonly used in wood processing and other fields.

Composite base sand belt: made of paper and cloth by bonding method, combining the advantages of cloth and paper, with high strength, small elongation, small deformation and other characteristics, suitable for high durability and grinding quality occasions.

Non-woven sanding belt: non-woven fabric is made of cotton fiber or synthetic fiber carding, itself has almost no tensile strength, so it is usually combined with other substrates to make sanding belt. The abrasive belt has good surface elasticity and good polishing properties.
