Gasket Sheets by Temperature up to 450 °C
For applications requiring gasket sheets capable of withstanding temperatures up to 450°C (842°F), specialized high-temperature materials are necessary. Here are some common gasket sheet materials suitable for temperatures up to 450°C:
Graphite:
- Graphite gasket sheets are known for their exceptional thermal stability and can withstand temperatures up to 450°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.
Metal (e.g., Stainless Steel):
- Metal-reinforced gasket sheets, such as those reinforced with stainless steel or other alloys, can withstand temperatures up to 450°C. These sheets offer excellent mechanical strength and stability, making them suitable for high-pressure and high-temperature sealing applications.
Ceramic Fiber:
- Ceramic fiber gasket sheets offer excellent thermal stability and can handle temperatures up to 450°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.
PTFE (Polytetrafluoroethylene):
- PTFE gasket sheets, including expanded PTFE, can handle temperatures up to 450°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.
Metal with Graphite Facing:
- Gasket sheets made from metal with graphite facing can withstand temperatures up to 450°C. These sheets combine the high-temperature resistance of graphite with the mechanical strength of metal, making them suitable for demanding sealing applications.
When selecting gasket sheets for temperatures up to 450°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.
