The vulcanized fiber is widely used in the grinding industry for its exnt strength and flexibility . The abrasive disc is made from vulcanized fiber using resin binder . The abrasive disc is widely used in shipbuilding , automobiles, machinery industries by applying on a variety of complex surface to remove rust, paint and to deburring and grinding welds. Our abrasive vulcanized fiber is made from 100% cotton refining pulp through our advanced equipments and process to overcome the common shortages of abrasive vulcanized fiber to become uniform , no distortion , no fracture and high safety factor .
