Silicone Foam EV Battery Flame Retardant Materials Silicone Foam Sheet


Our silicone foam is designed to enhance the safety and performance of EV batteries. With its fast curing properties, primerless adhesion, and medium density closed-cell structure, it offers excellent flame retardancy and thermal insulation. The wide operating temperature range of -50 °C to 200+ °C makes it suitable for harsh environments.

Flame Retardant: Meets stringent fire safety standards, providing a reliable barrier against flames.


1. Thermally Insulative:** Helps maintain optimal battery temperatures by reducing heat transfer.


2. Lightweight:** Minimizes the addition of weight to the battery pack, preserving vehicle efficiency.


3. Noise Dampening:** Reduces vibration and noise, contributing to a quieter driving experience.


4. Cushioning Properties:** Offers protection against mechanical shocks and impacts.


Applications:

1. Thermal Insulation:** Silicone foam is used as an insulating material between battery cells to maintain optimal operating temperatures and prevent overheating, which can lead to thermal runaway and reduced battery life.


2. Fire Retardancy:** Due to its flame-retardant properties, silicone foam is employed in battery packs as a safety measure to reduce the risk of fire in the event of a short circuit or other electrical faults.


3. Vibration Dampening:** The cushioning properties of silicone foam help absorb vibrations and shocks during vehicle operation, protecting the battery cells from mechanical stress and potential damage.


4. Sealing and Gasketing:** Silicone foam is used to create seals and gaskets within the battery pack to prevent the ingress of moisture, dust, and other contaminants that can affect battery performance and longevity.


5. Gap Filling:** In battery modules, silicone foam is used to fill gaps between cells or components, ensuring uniform thermal management and reducing the risk of hot spots.


6. Compression Pads:** Silicone foam compression pads are employed in pouch-cell battery packs to apply moderate pressure on the cells, ensuring proper electrical and thermal connections while allowing the battery to 'breathe' during charge and discharge cycles.


Our silicone foam is a crucial component for EV manufacturers seeking to improve battery safety and performance while adhering to environmental and safety regulations. For more information or to request a sample, please contact our silicone experts.
