When it comes to coated abrasives, the backing is an essential component of the product. backing, also known as the substrate, refers to the carrier material on which the abrasive material is coated. The backing provides a foundation for the abrasive material and helps to support the abrasive grains during use.


Paper backing is the most common type of backing used in coated abrasives. It is made from a thin layer of paper that is coated with resin or glue to provide strength and durability. Paper backing is lightweight and flexible, making it ideal for use on contoured surfaces. It is also relatively inexpensive, making it a popular choice for a wide range of applications.


Cloth backing is another popular option for coated abrasives. It is made from a woven fabric, typically cotton or polyester, that is coated with resin or glue. Cloth backing is more durable than paper backing and can withstand higher temperatures and pressures. It is also more resistant to tearing and shredding, making it a good choice for heavy-duty applications.

Composite Backing: This type of backing is formed by bonding an E-paper backing with a cloth backing. It provides excellent load-bearing capacity and a flat base, offering better flexibility than paper backing.


Fiber Backing: Fiber backing is a combination of hardened paper and cotton cloth. It is commonly used to create stiff sanding discs with thicknesses of 0.6mm, 0.8mm, and 1.0mm. Thicker fiber backings are suitable for heavy-duty cutting applications, while thinner backings are used to produce more flexible sanding discs.


By understanding the different types of backings available, the right coated abrasive can be selected for your specific needs and achieve the best possible results.
