Features of Ceramic Fiber Insulation Board

Low Thermal Conductivity

Ceramic fiber thermal insulation board has low thermal conductivity, which means they effectively resist heat transfer. This property makes them excellent choices for applications requiring insulation against high temperatures.

Excellent Elasticity

These boards exhibit remarkable elasticity, allowing them to withstand mechanical stress and deformation. Their flexibility makes them suitable for various installation configurations, ensuring optimal performance in different environments.

High Thermal Shock Stability

With excellent ceramic fiber board thermal conductivity, they can withstand rapid changes in changing temperature. This property is crucial in environments where sudden temperature fluctuations occur, which ensures long-term durability.

Good Resistance to Peeling

With strong adhesion properties, ceramic fire boards demonstrate good resistance to peeling in kiln linings. This feature ensures that the insulation remains intact over time, which maintains its effectiveness and structural integrity of the ceramic fiber textile.

Effective Sound Absorption

These refractory ceramic fiber boards offer effective sound absorption capabilities, dampening noise and reducing reverberation. This feature makes them suitable for applications where noise control is essential, such as in industrial settings or building construction.

High Toughness

The high temperature ceramic fiber boards exhibit high toughness, allowing them to withstand bending, flexing, and other mechanical stresses without breaking or crumbling. Their resilience ensures long-lasting performance even in demanding conditions.
