Application
Our fiberglass backing flap disc is often used for welding seam polishing and deburring of metal, stainless steel and so on, and for polishing wood materials. Compared to plastic backing, the fiberglass backing flap disc is safer, making it ideal for use in high-strength industrial applications, such as metal manufacturing and construction industries.

1. We use high-strength fiberglass backing plate. The fiberglass mesh used is comprised of more than 5 layers, which makes it high temperature resistant and features an excellent safety.

2. Using a high-temperature calcined abrasive cloth, the sand is subjected to high-temperature calcination, thereby significantly improving the hardness and wear resistance of the sand. The sharpness and wear resistance are both increased by more than 30% when compared to traditional abrasive cloths.

3. The flaps on the sanding discs are automatically overlapped by the machine. The workmanship is neat and smooth, so that there will be no broken flaps during usage.

4. The flap can be widened and thickened. For example, for a 4-inch flap disc, the general number of flaps is 72, with the length of 22mm and the width of 14mm. When the customer requests the number of flaps to be added to 80, the length and width of the flap can also be increased, usually by 2-3mm. The abrasion resistance will also increase by 50%.
