Adhesive Tape Solutions for Battery Venting

Venting adhesives must hold under stress, but release when the system requires it. Our anisotropic filmic tapes are tuned to respond to directional-dependent flame.  This engineered failure mode ensures venting occurs precisely when needed, minimizing collateral damage to the battery structure and surrounding vehicle components.

Battery venting system requirements vary by architecture:

• Sealed battery packs require adhesives that function as permanent barriers, chemically resistant, heat stable, and vibration-tolerant across the service life.

• Vented packs require adhesives that maintain bond strength under normal operation but release cleanly under elevated pressure or heat.

We offer adhesive constructions optimized for both use cases, with material options and release thresholds adapted to customer design intent.

These applications demand performance across multiple axes. Our solutions are developed to address:

• Controlled release: Precise activation under targeted load conditions, no premature or delayed failure.
• Thermal and chemical exposure: Stability in contact with electrolyte vapors, pressure, and thermal cycling.
• Multi-material bonding: Proven adhesion across battery-relevant substrates: aluminum, polycarbonate, PET, foils, membranes.
• Aging resistance: Designed for consistent behavior at end-of-life, not just day one.

We collaborate with engineering teams to integrate materials seamlessly into evolving battery architectures.

We offer multiple material platforms to meet pack-level performance targets:

• Anisotropic acrylic tapes: Engineered directional release, thermally stable.

• Double-coated foam adhesives: Absorb vibration and allow for vent integration.

• Transfer adhesives: Thin-profile, low-mass bonding with strong adhesion.

• Laminated films: Reinforced structures for pressure management and system stability.

Battery venting is a safety-critical system function. Our adhesives are validated under real-world simulations, including:

• Thermal cycling and humidity aging

• Peel, tack, and shear strength across materials

• Compatibility with common electrolytes and chemical exposure

• Consistent, predictable failure behavior
  

Testing is conducted in ISO 9000 and ISO 17025-certified labs. Many of our solutions meet UL® standards. We also support custom test protocols and integration guidance for customer-specific requirements.
