Ultra-high temperature ceramic fiber board, 1800℃ resistance, core thermal insulation material

Ultra-High Temperature Ceramic Fiber Board

The ultra-high temperature ceramic fiber board breaks through the temperature resistance limit of traditional materials. It maintains extremely low thermal conductivity even under ultra-high temperatures, featuring excellent thermal insulation efficiency. This can significantly reduce the temperature of the equipment shell, improving safety and energy efficiency. It also has excellent thermal shock resistance, being able to withstand severe temperature changes without cracking or peeling; its low heat capacity design accelerates the heating and cooling of the equipment.

Key Terms Explained:

Maximum Service Temperature: The absolute highest temperature the material can be exposed to for short periods.
Long-Term Use Temperature: The recommended maximum temperature for continuous, safe operation without significant degradation.
Bulk Density: The mass per unit volume. Lower density often indicates better insulation but may affect mechanical strength.
Thermal Conductivity: A measure of how well the material conducts heat. Lower values mean better insulation performance.
Linear Shrinkage on Heating: The percentage by which the material permanently contracts when heated to a specific temperature. Lower values are better, indicating greater dimensional stability.
