LithiumPrevent 200REX
LithiumPrevent 200REX is an extrudable fire safety solution for lithium-ion batteries.
LithiumPrevent 200REX gives OEM engineers new design freedom to integrate passive fire protection into continuous profiles, sheets, panels, and complex geometries.
Design Flexibility:
Create continuous shapes and custom profiles to fit unique battery architectures.
Scalability for OEMs:
Efficient large-scale production with reduced tooling costs.
Seamless Integration:
Easily incorporate extruded fire protection barriers into module housings, spacers, or enclosures.
Lightweight & Consistent:
Uniform extruded components deliver reliable material performance across the entire assembly.
Fewer Parts & Reduced Complexity:
Multiple features and functions can be integrated into a single continuous profile, minimizing part count and simplifying assembly. This reduces manufacturing complexity and assembly time while lowering costs and the risk of errors.
LithiumPrevent 200REX features the same proprietary intumescent technology as other LithiumPrevent formulations, delivering trusted protection against lithium-ion battery hazards:
• Contains thermal runaway at the cell or module level.
• Provides thermal separation between cells and modules.
• Controls explosive pressure events.
• Prevents cascading fire propagation.
• Blocks heat transfer to adjacent combustibles.
• Absorbs Heat
• Forms a Char
• Blocks Fire
• Stops Arcing
• Prevents Smoke Induced
Current Paths
• Cell Containment
• Busbar Isolation
• Pack Lid Defense
