What happens if ceramic fiber board gets wet?

In high-temperature insulation applications, ceramic fiber board is widely used for its excellent thermal resistance and insulation performance. However, in real-world conditions, moisture exposure can pose a significant risk. Once a ceramic fiber board gets wet, it may lose structural strength, reduce insulation efficiency, and even suffer from physical damage. So, what actually happens when a ceramic fiber board gets wet—and how can we prevent it?

This is where CCEWOOL Water Repellent ceramic fiber board offers a reliable solution.

The Risk of Water Damage: A Hidden Weakness in Traditional Ceramic Fiber Board

When standard ceramic fiber boards absorb moisture, they tend to swell, become brittle, or disintegrate. Their thermal conductivity increases, drastically reducing insulation effectiveness. Moreover, in high-temperature operations, residual moisture can vaporize and cause micro-explosions, leading to instability and performance degradation. This is especially problematic in outdoor installations or humid working environments.

CCEWOOL Water Repellent Ceramic Fiber Board: Consistent Performance, Even in Moisture

To meet the demands of challenging operating conditions, CCEWOOL developed a Water Repellent ceramic fiber board that incorporates a specialized water-repellent additive into its high-purity ceramic fiber base:

Water-Repellent Surface

A dense protective layer prevents moisture absorption, ensuring the board maintains its integrity even in prolonged humid environments.

Thermal Stability Maintained

Even after drying from moisture exposure, the board retains its excellent insulation and thermal shock resistance with no performance loss.

High Mechanical Strength

Resists deformation, cracking, or delamination caused by water damage—resulting in a more secure and stable installation.

CCEWOOL Water Repellent ceramic fiber board has been supplied to industrial clients in over 30 countries, receiving consistently positive feedback. Our product is certified by multiple international quality standards and can be customized in both size level to suit different application needs.
