Silicone Solutions for the electric vehicle (EV) and battery industry

In electric vehicle (EV) battery packs, silicone foam seals serve a crucial function by forming a barrier between the upper and lower housings, thereby preventing the ingress of water, dust, moisture, and salt.

These seals are essential not only for protection against environmental factors but also for a variety of additional purposes. They play a key role in managing and regulating the heat generated by the battery pack, preventing the unintended release of gases and liquids, and mitigating noise and vibration. Furthermore, these seals are designed for repeated disassembly and reassembly, meet the UL 94 V-0 requirements for safety, and are suitable for long-term use, making them an integral component in the durability and efficiency of EV battery packs.
