Non-asbestos gaskets are a type of sealing material used to prevent the leakage of gases or fluids in various industrial applications. They are made from a combination of synthetic fibers, fillers, and binders, which provide excellent sealing properties without using asbestos fibers.
Asbestos was a commonly used material in gaskets due to its heat-resistant properties, but it is now widely recognized as a hazardous material that can cause serious health problems. Non-asbestos gaskets provide a safer and more environmentally friendly alternative without compromising on performance.
One of the main benefits of non-asbestos gaskets is their ability to withstand high temperatures and pressures, making them ideal for use in demanding industrial applications. They are also resistant to a wide range of chemicals, which ensures that they maintain their sealing properties even when exposed to harsh environments.
Non-asbestos gaskets come in a variety of types, including compressed sheet gaskets, spiral wound gaskets, and ring joint gaskets. Compressed sheet gaskets are made from a blend of synthetic fibers and elastomers that are compressed to form a strong, flexible sheet. Spiral wound gaskets are made from alternating layers of metal and non-asbestos filler material, which provide excellent sealing properties even in high-pressure applications. Ring joint gaskets are used in high-pressure and high-temperature applications and are made from a combination of metal and non-asbestos filler material.
Non-Asbestos gaskets come in a variety of basic materials comprised of carbon, graphite, fiberglass, aramid fiber, kevlar and other mineral fibers. The basic components of the non-asbestos materialis used in gasket construction are elastomer and filler. Add special adhesives and a litle packing into it, then roll and sulfurated. The elastomer composition corresponds to the application of the gasket, assisting in the categorization and selection of the gasket best used for the service it will be performing.
