High Performance Sealing Solution
EV Battery Rubber Gasket is a high-performance sealing solution specifically designed for electric vehicle battery systems. These premium rubber gaskets ensure optimal protection, thermal management, and long-term reliability for EV battery packs operating under demanding conditions.
Product Description
Our Electric Vehicle Battery Rubber Gaskets are engineered to meet the demanding requirements of modern EV battery systems. These sealing components provide comprehensive protection against environmental exposure while maintaining stable performance under extreme temperatures and long-term compression.
Designed with advanced rubber formulations and precision manufacturing processes, the gaskets offer superior sealing performance, electrical insulation, vibration damping, and thermal management for passenger EVs, commercial vehicles, and energy storage systems.
Key Features & Functions
1. Environmental Sealing
Provides complete protection against water ingress (IP67/IP68), dust, moisture, road salt, and contaminants, ensuring battery system integrity in all weather conditions.
2. Thermal Management
Excellent thermal insulation maintains optimal battery operating temperatures. Silicone foam options enhance heat dissipation and vibration dampening.
3. Fire Resistance
Meets UL 94 V-0 flame retardant standards. Optional nickel-graphite fillers provide passive fire protection during thermal runaway events.
4. EMI Shielding
Conductive elastomer options effectively block electromagnetic interference, ensuring stable communication between battery systems.
5. Compression Set Resistance
Maintains sealing force under long-term compression, delivering reliable performance throughout the battery lifecycle.
6. Easy Installation
Compatible with automated assembly lines. Adhesive backing and custom profiles available for various mounting designs.
