Protect battery cells from fire, heat and rebounding particles
ContraFlame® F4- Series is a lightweight rebound protection foam for high density prismatic and cylindrical battery cells, offering protection during thermal runaway and extreme fire events. In the event of a cell undergoing thermal runaway, the material allows the cell to vent safely by allowing hot gases and particles to break through whilst shielding neighbouring cells from rebounding particles.

Control thermal runaway and protect neighbouring cells
The F4- Series helps reduce the risk of thermal runaway propagation by controlling hot gases and rebounding particles within the battery module. Lightweight, low-outgassing foams can be applied directly to cells and accommodate different battery geometries and manufacturing requirements.
Specifications
When exposed to high temperatures the material rapidly forms a tough char that will resist erosion by high velocity or turbulent gasses, while continuing to provide insulation to protect the substrate. Even when using the most agressive battery cells (cylindrical 46xx, prismatic >150 Ah), ContraFlame® F4- Series provides additional safety.
- Easy application and efficient replacement to pre-formed mica products
- Cures at room temperature within 30 minutes
- Tested and proven protection of 46xx cells and >150 Ah prismatic cells
- Extreme resistance to flames and rebounding particles
- Low outgassing formulation
- Adhesion capabilities on metals allows direct application onto the cells
- Mass-scale application tested and verified at mixing and dosing equipment manufacturers.
