Common Sealing Materials :
🔹 Liquid Gasket – Flexible, easy to apply, and offers excellent waterproof and dustproof properties.
🔹 Foam Gasket – High elasticity, water-resistant, and effective in reducing vibrations.
🔹 Silicone Sealant – Heat-resistant, chemical-resistant, and excellent electrical insulation.
🔹 Polyurethane Sealant (PU Sealant) – Strong adhesion, providing robust protection in harsh environments.

✅ Waterproof & Dustproof (High IP Rating) – Protects the battery from moisture, water, and dust, ensuring long-term stable operation.
✅ Leak Prevention & Component Protection – Prevents harmful substances from entering, maintaining battery performance.
✅ Fire Resistance & Insulation – Some sealing materials are UL94-V0 certified for fire resistance and provide excellent electrical insulation, reducing short-circuit risks.
✅ Vibration & Shock Absorption – Helps secure the battery pack housing, minimizing mechanical impact from the external environment.
