Sandpaper (Paper)
Sandpaper, also known as emery paper, is a strong and versatile material used in a wide range of different applications. It is made up of multiple materials, including abrasive particles and a paper or cloth-like backing. Depending on the formulation and grain size, sandpaper can be used to smooth, polish, and clean many different surfaces. From cleaning the bathroom tile to smoothing out shaped wood, it is a valuable tool in both professional work settings and common household tasks.
When manufacturing sandpaper, manufacturers use a variety of materials to create the backing and grain materials. Different abrasives are used to create a range of grit sizes. Aluminum oxide, silicon carbide, and garnet are most commonly used for wood working and metal finishing as they have sharp edges and strong cutting ability. For softer materials, succelastic and foam can be used as the backing materiel to create a softer sandpaper.
Manufacturer and Types
Sandpaper is manufactured by a variety of companies in a wide variety of sizes and materials. 3M, Norton/Saint-Gobain, and Klingspor are some of the more popular brands that make sandpaper. Many of them offer different grades of paper and cloth-backed sandpaper that correspond to International Standards Organization (ISO) and American National Standards Institute (ANSI) standards. These standards designate the type and size of abrasive particles and the corresponding ratings for strength and durability.
Grit Sizes
Depending on the type of work that is being done, different sizes of sandpaper are used. Sandpaper is available from extra-coarse, P-grade 20 grit to ultra-fine 800 grit. The lower grade grits are designed for quickly removing material and rough shaping. High grade grits are used for finishing and polishing surfaces to a smooth finish.
Sandpaper is a valuable tool for a wide range of projects and tasks. Whether it is used to clean, sand, polish, or finish, it is an indispensable tool for the home and shop. By understanding the different types, sizes, and ratings of sandpaper, it is easier to pick the right material and grit to get the job done right.
