Avery Dennison Hanita offers cutting-edge flame retardant solutions specifically engineered to address the challenges of thermal runaway propagation. These innovative materials are versatile and can be seamlessly integrated into various critical areas of the battery system. For instance, our flame retardant films are ideal for high-performance tapes or bags, which can be applied directly to battery cells or modules, and as the encapsulation substrates for the insulation materials, providing an additional layer of protection. By slowing the propagation process of thermal runaway, our solutions offer invaluable time for safety systems to activate, significantly enhancing overall vehicle safety.

At the core of effective thermal management strategies are high-temperature, flame-retardant films. These films represent a proven and economically viable method for isolating individual battery cells from adjacent components and modules and separating different battery modules within a pack. This strategic isolation plays a crucial role in mitigating the risk of thermal runaway propagation from a single cell or module to the entire battery system, thereby substantially reducing the overall fire risk. The inherent flame-retardant properties of these materials act as a robust barrier, containing thermal events and preventing uncontrolled chain reactions.

Our high-performance 12 and 23 micron PET films offer comprehensive protection with their proprietary flame retardant coating on one or both sides. These films are available in white, translucent, and metallized and provide aesthetic and functional versatility to meet diverse design specifications. They are also REACH/RoHS compliant and achieve a UL 94-VTM – 0 flame retardancy equivalent.

By leveraging Avery Dennison Hanita's innovative flame retardant solutions, EV manufacturers can significantly enhance their battery systems' safety, reliability, and performance, paving the way for a more secure and sustainable electric mobility future.
