What types of grain are used in the production of nonwoven material?
• Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications. • Silicon Carbide – Silicon Carbide is black in color. It is a sharp, hard synthetic abrasive. Its friable grains fracture to continually expose new cutting edges and permit fast stock removal. It cuts fast and produces finer scratch patterns. How do nonwoven abrasives work? Nonwoven abrasives provide a controlled, sustained stock removal process. The “open weave” three-dimensional material construction provides a continuous supply of new grain when fiber and old grain wear away. The flexible “spring” design reduces the chance of undercutting or gouging a work product. Nonwoven abrasives can be divided into two categories: • Clean & Finish – Nonwoven clean & finish products are generally hand-operated. The are not as strong in nature as surface conditioning products because less g
