Expandable Fiber Paper (2300°F)

An expandable ceramic fiber paper gasket is a type of gasket made from ceramic fibers that can expand or swell when exposed to heat. These gaskets are used in high-temperature applications where sealing is needed, such as in furnaces, industrial boilers, or exhaust systems. The ceramic fiber material is known for its excellent thermal insulation, high-temperature resistance, and durability.

Here are some key characteristics of expandable ceramic fiber paper gaskets:

1. Thermal Insulation: They can withstand extremely high temperatures, typically in the range of 1,000°F to 2,000°F (537°C to 1,093°C), making them ideal for use in heat-intensive environments.
2. Expandable Properties: The gasket expands when subjected to heat, which can provide a better seal and compensate for any potential gaps or changes in the mating surfaces over time.
3. Flexible and Lightweight: Ceramic fiber is flexible and lightweight, which makes it easy to cut, shape, and handle.
4. Chemical Resistance: It is resistant to a wide range of chemicals, which increases its versatility for use in various industrial applications.
5. Fire and Heat Resistance: Ceramic fibers are non-flammable and can endure prolonged exposure to heat without degrading.

These gaskets are typically used in sealing applications where conventional materials might fail due to extreme temperatures, such as in high-heat exchangers, boilers, or even in some automotive applications.
