1. They do not melt.
2. They exhibit no significant shrinkage.
3. They retain their thermal insulation capabilities.
First, ceramic fiber blankets are primarily composed of aluminum oxide (Al₂O₃) and silicon dioxide (SiO₂)—materials that are inherently "naturally resistant to high temperatures." Furthermore, ceramic fiber consists of a porous structure formed by the interweaving of countless fine fibers; this design facilitates the easy dissipation of thermal stress, provides ample space for thermal expansion, and incorporates numerous air pockets. The following details the temperature resistance capabilities of various ceramic fiber grades:
If you have industrial requirements for high-temperature resistance—such as in ceramic kilns, boilers, or hot air ducts—ceramic fiber blankets are a highly recommended choice.
