Product introduction of ceramic fiber cotton
Ceramic fibers cotton are highly efficient heat insulating materials, such as light weight, high strength, antioxidation, low thermal conductivity, flexibility, corrosion resistance, heat capacity, and sound insulation.
Features of ceramic fiber cotton
- Excellent sound absorption and fire prevention performance
- Excellent in corrosion and mechanical impact
- Low heat capacity, low heat conductivity, high fire resistance, high sensitivity
- Use it in a neutral and oxidizing atmosphere without any
- The color is white, the size is accurate, the installation is easy, the construction is convenient, and the number of steps is saved
Applications of ceramic fiber cotton
Industrial kiln furnace, boiler, and thermal insulation
Thermal insulation of heat facilities for steam engines and gas engines
Flexible high temperature pipe insulation material High temperature spacer High temperature filtration
