Norton Bear-Tex Rapid Strip discs are suitable for removing surface defects, light edge burrs, parting lines, and flashing, and perform well in difficult-to-reach areas due to the conformable design. This disc features a resin bond. Resin bonds have good moisture resistance, are harder and less flexible than glue bonds, and have good heat resistance and grain retention. Resin bonds are useful for abrasive operations with high operating speeds, impact, and sudden loading, as the resin bond is strong and waterproof. Nylon fiber does not rust and is waterproof. Silicon carbide is a sharp, aggressive grain that offers high penetration, fast cutting, and high material removal even under light pressure. It is commonly used with softer materials like brass, plastics, and rubber, and abrasive materials like glass and enamel, but can wear out faster that aluminum oxide when used on wood. Non-woven abrasives have individual abrasive grains interspersed throughout an open web of nylon fibers. Open web construction produces a cushioned, three-dimensional material that is pliable, long-lasting, and will not rust. The uniform dispersion of abrasive throughout the web provides a supply of new grain as the old grain and fibers wear away during use. The nylon web is waterproof and washable. In non-woven abrasives, the grit is designated with a letter code, from Extra Coarse (XC) to Microfine (MF). Norton Abrasives manufactures a wide variety of sanding, grinding, and polishing abrasives, and has been located in the United States since 1885. In 1990, Saint-Gobain purchased Norton, keeping its manufacturing facilities and offices in the same location. Norton/Saint-Gobain has been recognized as a Global 100 Sustainable Company, as well as earning ISO 9000 and 14001 certification for quality and environmental management standards.
