3M lapping film roll 364M is used to create discs, belts and other abrasives designed for flat lapping and finishing on glass, vision wear and fiber optics. It features aluminum oxide abrasive grains bonded to a flexible polyester film backing. This fast cutting design produces a fine, uniform finish even on contoured surfaces. Abrasives made with 3M lapping film roll 364M are designed to provide a uniform, consistent finish of optical fiber connectors and end tips to ensure efficient signal transmission. It is resin bonded and supports disc flexibility without sacrificing durability and reliable performance under high heat and pressure. To complement the effective abrasive action, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable paper products, making it ideal for high production environments. 3M lapping film roll 364M features aluminum oxide abrasive grain, which is a popular choice among industrial professionals because of its fast cut rate and long useful life span. This mineral is a tough, durable abrasive that self fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut rate, hardness and strength, it is widely used for a variety of sanding and finishing applications. Heat-resistance bonding. The 364M film uses a resin bonding which is specially designed to resist thermal and chemical deterioration, which can occur during lapping and finishing. That heat-resistance is especially important when working on sensitive surfaces like glass. The toughness of this type of bond allows for faster sanding at a higher cut rate and makes it excellent for precision work on both hard and soft surfaces.
