Insulation films
Conformable silicone, PU and EVA foam materials designed to manage mechanical stresses throughout the battery lifecycle. Die-cut to customized shape, they are available in a range of thicknesses and densities, and compatible with thermal interface materials and structural adhesives.
Electrical short circuits are among the most critical failure modes in EV battery packs — whether in normal operation or following mechanical impact. Adhex EV battery insulation films provide reliable dielectric protection between cells, modules and structural components, maintaining electrical isolation even under deformation.
UL-94 rated and compatible with structural adhesives and gap fillers, they integrate seamlessly into automated assembly processes for cylindrical, prismatic and pouch cell formats.
