Transportation Electrification

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.

Transportation Electrification

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.

Silicone Performance Properties Critical to the Transportation Electrification Industry

Thermal Stability: Can withstand a wide range of temperatures without degrading, which is essential for components that operate in the high-temperature environments typical of electric vehicles.

Electrical Insulation: Has excellent electrical insulation properties, making it ideal for protecting sensitive electronic components in EVs from electrical interference and short circuits.

Flexibility and Durability: Aids in absorbing vibrations and shocks, which is crucial for EVs as it ensures the longevity of various components under dynamic stress.

Chemical Resistance: Resists degradation from various chemicals, including oils and solvents, which is important for maintaining the integrity of EV components exposed to these substances.

Low Toxicity and Environmental Impact: Non-toxic and does not release harmful substances, which aligns with the environmentally friendly ethos of the electric vehicle industry.

Weather and UV Resistance: Resistant to weathering and UV radiation, ensuring that components maintain their integrity and performance even under harsh environmental conditions.

Flame Retardancy: Flame retardant, which is critical for safety in electrical applications, particularly in vehicles.

Thermal Conductivity: Excellent thermal insulators, engineered to conduct and dissipate heat from electronic components in EVs.

Compression Set Resistance: Silicone maintains its shape and elasticity even after prolonged compressive stress, which is vital for sealing applications in EVs.

Adhesion Properties: Silicone can adhere well to a variety of substrates, which is useful in bonding and sealing applications in electric vehicles.
