Non-asbestos gaskets are modern sealing materials designed to replace traditional asbestos-based gaskets, offering excellent sealing performance without the health risks associated with asbestos fibers. These gaskets are made from a blend of synthetic fibers, aramid fibers, glass fibers, and elastomeric binders such as NBR (nitrile rubber), SBR (styrene-butadiene rubber), or EPDM.
One of the main advantages of non-asbestos gaskets is their superior safety profile. Unlike asbestos materials, they do not release hazardous fibers, making them safe for workers during manufacturing, installation, and maintenance. Despite the absence of asbestos, these gaskets maintain excellent heat resistance, chemical resistance, and mechanical strength, making them suitable for sealing applications in industries such as chemical processing, oil and gas, power generation, and marine engineering.
Non-asbestos gaskets are commonly used for sealing flanges, pumps, valves, and heat exchangers in both low and high-pressure environments. They can handle a wide range of media, including steam, oils, fuels, gases, and various chemicals, depending on the specific formulation and binder used.
In addition to their sealing capabilities, non-asbestos gaskets offer good compressibility and recovery properties, ensuring a tight and reliable seal even under fluctuating temperature and pressure conditions. They are also resistant to aging, deformation, and creep, providing long-term performance and reducing the need for frequent maintenance or replacement.
Overall, non-asbestos gaskets provide a safe, cost-effective, and environmentally friendly sealing solution for a variety of demanding industrial applications.
