Ceramic Fiber Aerogel Sealed Thermal Insulation Pad
Product Description
The ceramic fiber aerogel sealed thermal insulation pad is manufactured using high-temperature-resistant ceramic fiber composite technology. Through processes such as impregnation, solidification, drying, and precise lamination, the material achieves excellent high-temperature resistance, low thermal conductivity, and highly stable insulation performance.
It is widely used for high-temperature thermal insulation and fire protection of electric vehicle battery cells and modules, as well as in industrial equipment, pipelines, energy storage systems, and intelligent control components.
Product Features
Excellent thermal insulation: Extremely low thermal conductivity ensures effective thermal barrier performance.
High-temperature resistance: Stable structure, non-melting, and non-deforming under long-term high-temperature exposure.
Lightweight and flexible: Easy to process and cut; suitable for various installation methods.
Waterproof and moisture-resistant: Hydrophobic and moisture-resistant surface; does not absorb water.
Environmentally friendly: Non-toxic, odorless, and compliant with environmental safety standards.
Strong flame retardancy: Acts as an effective thermal runaway protection barrier for EV batteries.
