Improve & Manage Structure
Optimise space within the pack without compromising the pack's mechanical integrity. Protect cells and circuitry from potentially damaging vibrations caused by road conditions and driving patterns.
Assembly and Attachment Tapes
Assembly and attachment tapes are not only lightweight, but they facilitate EV design due to their ability to bond many types of materials. They can be specially tailored and customised to match the requirements for a particular assembly type or speed. With high dielectric strength, high energy absorption capacity, tailored tack and adhesion, acrylic and polyurethane tapes improve the structural integrity of the battery pack. They enable flexible automotive bonding, providing the strong holding power EV applications require. Additionally, they offer a range of options for attaching cells and the casing and are highly adaptable to automated assembly processes.

Cushioning Pads and Damping Foams
Cushioning pads and dampening foams are low-density materials that have the ability to reduce mechanical vibrations and maintain flexibility, form, and function throughout the lifetime of the battery pack. They act as a spring, ensuring continuous contact between the heat source (battery module) and heat sink (cooling plate) over the lifetime of the battery, thereby supporting the thermal pad's heat dissipation function. Not only are they cost-effective, but they also offer superior flame retardancy performance for enhanced passenger safety.
