For applications requiring gasket sheets capable of withstanding temperatures up to 300°C (572°F), specialized materials with high-temperature resistance are necessary. Here are some common gasket sheet materials suitable for temperatures up to 300°C:

1. Graphite:

   • Graphite gasket sheets are known for their excellent thermal stability and can withstand temperatures up to 300°C due to graphite’s high thermal conductivity and resistance to oxidation. These sheets are commonly used in high-temperature sealing applications such as in steam systems, chemical processing, and refineries.

2. Ceramic Fiber:

   • Ceramic fiber gasket sheets offer exceptional thermal stability and can handle temperatures up to 300°C. These sheets are lightweight and have low thermal conductivity, making them suitable for high-temperature sealing applications such as in furnaces, kilns, and exhaust systems.

3. Mica:

   • Mica gasket sheets can withstand temperatures up to 300°C due to mica’s excellent thermal insulation and resistance to high temperatures. These sheets are commonly used in electrical and thermal insulation applications, as well as in high-temperature sealing applications.

4. Metal (e.g., Stainless Steel):

   • Metal-reinforced gasket sheets, such as those reinforced with stainless steel, can withstand temperatures up to 300°C. These sheets offer excellent mechanical strength and stability, making them suitable for high-pressure and high-temperature sealing applications.

5. PTFE (Polytetrafluoroethylene):

   • PTFE gasket sheets, including expanded PTFE, can handle temperatures up to 300°C without losing their sealing properties. PTFE is chemically inert and resistant to a wide range of fluids, making it suitable for high-temperature and corrosive environments.

When selecting gasket sheets for temperatures up to 300°C, it’s crucial to consider factors such as pressure, chemical compatibility, surface roughness, and specific application requirements to ensure optimal performance and sealing effectiveness. Additionally, different grades and formulations of these materials may offer varying temperature capabilities and other properties, so consulting with a gasket manufacturer or supplier can help in choosing the right material for your needs.
