It is made of rubber & plastic macromolecule material, corundum and silicon carbide, soft and flexible. It has good wear resistance. Choosing suitable hardness andgrit No. as per material & surface of work parts; Especially the uneven surface and curved surface, it can get ideal brightness without damage after polishing. It is difficult for common grinding wheels to get such good effect.
