Ceramifiable / Fire Barrier Silicone Foam

SA700-350-C is a ceramicified thermal insulation silicone foam that combines the flexibility of silicone, the compressibility and resilience of foam, and the extreme high-temperature resistance of a ceramic phase. At room temperature, it provides excellent sealing, damping, and thermal insulation. When exposed to open flames or temperatures above 500°C, it rapidly transforms into a rigid and dense porous ceramic protective layer that helps block flames and heat, making it suitable for EV batteries, energy storage systems, fire barriers, and safety partition structures.

Technical Information

Review the product positioning, technical data, thermal barrier performance, compression behavior, applications, and handling guidance for SA700-350-C ceramifiable silicone foam.

Q1

What is SA700-350-C designed to solve?

SA700-350-C is designed for structures that require sealing, thermal insulation, damping, and fire-barrier performance in one material—especially in EV battery packs, energy storage systems, and related safety partitions.

Ceramifiable Foam Direction

At room temperature it behaves as a compressible silicone foam; under flame or high heat it converts into a rigid ceramic-like protective layer.

Fire Barrier + Safety Partition

Designed for EV batteries and ESS fire barrier structures where flame penetration and heat transfer must be slowed down.

Sealing + Damping

Supports room-temperature sealing and damping before fire or overheating exposure occurs.

Thermal Runaway Delay

The TDS explicitly states it is used in energy storage units and between power battery cells to delay thermal runaway propagation.

Q2

What are the key technical data for SA700-350-C?

The TDS provides the following values for screening thermal barrier, compression, insulation, and flame-retardant performance.

These values support preliminary comparison for sealing force, fire barrier design, and thermal insulation validation. Final qualification should still be based on the user’s real module stack-up and fire test method.

Q3

What functional strengths does SA700-350-C emphasize?

Its key strengths are thermal barrier formation, thermal insulation, compression resilience, sealing, and electrical insulation for fire-protection structures.

High-Temperature Ceramic Conversion

Transforms into a rigid ceramic body under high temperatures, providing a continuous thermal barrier.

Exceptional Thermal Insulation

Low cold-side temperature rise under flame exposure supports fire barrier and partition design.

Compression Resilience

Supports long-term sealing performance while still functioning as a foam structure before fire exposure.

Electrical Insulation

High insulation value makes it suitable for protected interfaces in battery and power-system structures.
