Summary

Freudenberg Sealing Technologies (FST) is dedicated to creating sustainable and resource-efficient products, particularly for the automotive industry’s shift toward electric vehicles. Their new product family, Thermal Barriers, aims to significantly reduce battery fires and mitigate thermal runaway propagation in lithium-ion batteries. These solutions enhance passenger safety during thermal events by shielding the interior from released thermal energy, guiding energy outward, reducing thermal propagation between cells, and ensuring electrical insulation. 
Thermal Barriers are applied at various levels, including cell, cell pack, and battery designs. They feature high-temperature resistant materials like silicone and thermo-plastic, which can be customized to fit specific areas and retrofitted into existing production lines or integrated into new designs. These products protect sensitive components such as fuses, connectors, and cooling systems, preventing damage and reducing thermal propagation. 
FST's advanced materials and manufacturing techniques, combined with flexible designs, create effective barriers that stop thermal propagation and allow for lightweight battery construction. Their modular systems enable quick customization to meet specific customer needs, offering mechanical properties and thermal insulating/flame protection for various cell types and chemistries. Freudenberg's innovative approach includes creating compressibility through calculated geometry and specially designed elastomer elements, resulting in products with flame barriers, thermal insulation, and adjustable compressibility.
