NVH Baffles

Because aluminum body panels expand at twice the rate that steel ones do, a new baffle sealing package was needed that would maintain adhesion to the substrate during thermal expansion of the aluminum. It also needed to reduce or eliminate NVH throughout the vehicle to improve driver comfort through a quieter interior. A new EVA expandable sealer with a blowing agent that activates during e-coat and produces an innovative elastic cross-linking network was developed to improve hot-tear strength and elongation vs. previous materials. The EVA foam is injection overmolded onto a PA substrate.
