Ceramic fiber gaskets represent a breakthrough in high-temperature sealing technology, engineered to withstand extreme thermal conditions while maintaining exceptional compression recovery. Composed of high-purity alumina-silicate fibers, these specialized gaskets operate continuously at temperatures up to 1260°C (2300°F), outperforming traditional graphite or asbestos gaskets by 3-5x in high-heat applications. With thermal conductivity as low as 0.12 W/m·K, ceramic fiber paper gaskets provide superior insulation while creating reliable seals in furnaces, boilers, and exhaust systems. Their unique needled fiber structure ensures excellent conformability to flange surfaces, even under significant thermal cycling and vibration conditions common in petrochemical and power generation operations.

Product Usage:
Ceramic fiber gaskets are versatile and find applications in a wide range of industries.
They are commonly used in high-temperature furnaces, kilns, and ovens to provide insulation and protect equipment from heat damage. In the petrochemical industry, these gaskets are used to insulate pipes and reactors, ensuring safe and efficient operation. They are also used in aerospace and automotive applications for thermal protection and insulation of critical components. Additionally, ceramic fiber paper gaskets are used in electrical applications as insulators and in fire protection systems.
Product Advantages
Ceramic fiber gaskets have low thermal conductivity, ensuring minimal heat transfer and efficient insulation. These gaskets also exhibit excellent thermal stability and chemical resistance, making them suitable for use in corrosive environments. Additionally, ceramic gaskets are lightweight and flexible, which simplifies installation and handling. They are also resistant to thermal shock, allowing them to withstand rapid temperature changes without degradation.
Product technology:
The manufacturing process of ceramic fiber gaskets involves several steps to ensure high quality and performance. High-purity alumina-silica fibers are spun into sheets or formed into gaskets using a wet molding process. The gaskets are then subjected to high-temperature treatment to enhance their thermal and mechanical properties. Each gasket is inspected for uniform density and structure to ensure consistent performance.
