The most common abrasive cloth is made of Zirconia grain, that provides the best grinding and finishing performance on most types of metals. Other abrasive cloths include Aluminum Oxide (general purpose use, lower price) and Ceramic-Zirconia (best results on stainless steel). Lower grits (40, 60) are more suitable for higher material removal, higher grits (80 and 120) provide better results in finishing.

The backing of the flap disc is a critical component, that can impact the performances and the safety of the disc itself. Sometimes, it’s importance is overlooked. The backing must be strong enough to hold the cloth, withstand different levels of pressure and allow the required grinding capacity. At the same time, it must be lightweight and well finished. The shape can be flat or convex. It can be made of fiberglass (7 to 10 layers of fiberglass nets glued with resin), or nylon. Possible alternatives, less common, are abs and metal (copper or aluminium).
Special adhesive for fixing the abrasive flaps on the fibreglass or nylon backing. It is a mono component epoxy adhesive, semi-solid, totally free from solvents, which is used with heated pressing flat dosing machines.
