Product Description
Ceramic Silicone Sponge Sheet KB1010CF is an advanced flame-retardant material designed for high safety and reliability in harsh environments. Formulated with a special ceramic-forming additive, this closed-cell silicone foam expands under extreme heat or fire conditions to form a ceramic-like protective layer, effectively preventing flame spread and maintaining structural integrity. KB1010CF offers excellent thermal insulation, low smoke emissions, and superior high-temperature resistance, making it an ideal choice for electric vehicle battery packs, energy storage systems, rail transportation, and aerospace applications. Its lightweight, resilient structure provides sealing, cushioning, and shock absorption while ensuring compliance with stringent fire protection standards.
Low compression set and high creep resistance
Excellent flame retardancy, low smoke density and toxicity, high oxygen index
High electrical insulation

Closed-cell silicone foam is used in a wide range of industries for sealing, insulation, cushioning, and flame protection. Its closed-cell structure prevents the passage of air, water, and dust, making it ideal for environmental sealing in harsh conditions. Common applications include:
EV battery pack protection and sealing
Thermal insulation and fire protection in energy storage cabinets
Gasketing in automotive and aerospace systems
Shock and vibration dampening in electronic devices
Weatherproof seals for outdoor equipment and enclosures
Because of its excellent temperature resistance, low compression set, and flame-retardant performance (UL94 V-0), it is trusted in critical and high-safety applications.
The main difference between closed and open-cell silicone foam lies in their internal structure and performance characteristics.
Features a compact structure where cells are completely enclosed, preventing air, water, and dust from passing through. This makes it ideal for sealing, insulation, and environmental protection in harsh conditions. It offers better water resistance, lower air permeability, and is commonly used in EV batteries, outdoor enclosures, and gaskets.
Has interconnected cells that allow air and moisture to flow through the material. It is softer, more compressible, and better for cushioning, sound absorption, and applications that require ventilation or breathability.
Closed-cell: Better sealing and protection
Open-cell: Better breathability and cushioning
Choosing the right type depends on your application's needs for moisture control, airflow, and mechanical performance.

When selecting Ceramic Silicone Sponge Sheet KB1010CF, consider the following factors based on your application needs:
KB1010CF is available in a range of thicknesses (typically 0.5 mm–30 mm). Choose the right thickness based on the gap size, compression level, and sealing performance required.
If your application involves high temperatures (up to 200°C) or fire safety standards like UL94 V-0, KB1010CF is an excellent choice due to its stable performance under extreme conditions.
Evaluate the compression set performance for applications requiring long-term sealing under pressure. KB1010CF offers excellent recovery and low compression set.
KB1010CF is resistant to UV, ozone, and moisture, making it ideal for outdoor or rugged environments like EV battery packs and energy storage units.
Determine if you need die-cut gaskets, adhesive backing, or laminated layers. KB1010CF supports customization for better fit and functionality in complex assemblies.
Ensure KB1010CF meets your regulatory needs, such as RoHS, REACH, or automotive flame-retardant standards.
If you're unsure, our technical team can help recommend the ideal density, thickness, and design configuration based on your product and industry needs.
