3. Composition Information

Ceramic fiber + SiO2 aerogel; PET

 

4. Key Features

Excellent insulation performance: Ultra-low thermal conductivity, highly effective thermal barrier.

Soft and flexible: Easy to bend and process, suitable for complex assembly spaces.

Waterproof and hydrophobic: No moisture absorption, maintains stability in humid environments.

High compressive resilience: Provides superior cushioning and compression resistance.

5. Applications

The silicone aerogel thermal pad is mainly used for thermal insulation and protection of new energy vehicle battery cells and modules.

When a single cell experiences thermal runaway, the thermal pad can effectively block heat transfer and delay propagation between cells, helping maintain system stability.

At the same time, it provides insulation, buffering, and flame-retardant properties.

 

6. Quality Assurance
