For high temperatures exceeding 1500 degrees Fahrenheit, which gasket material is commonly used?

Ceramic gaskets are commonly used for high-temperature applications, especially those exceeding 1500 degrees Fahrenheit. This is largely due to the material's ability to withstand extreme heat without degrading or losing its structural integrity. Ceramics offer excellent thermal resistance and can maintain their physical and chemical properties under severe conditions, making them ideal for environments such as industrial furnaces or combustion systems.

In contrast, rubber, silicone, and vinyl materials generally have lower temperature thresholds and can break down or lose effectiveness when exposed to high temperatures. Rubber gaskets might start to melt or produce harmful fumes at elevated temperatures, while silicone and vinyl also typically have maximum temperature ratings well below 1500 degrees Fahrenheit. Therefore, ceramic gaskets stand out as the most suitable choice for high-temperature sealing applications.
