Acoustic Solutions

All our solutions are customized to meet customer specific requirements. Whether it be sealing even the most complex cavities, minimizing vibrations, or providing lightweight insulation, all have one shared purpose: improving acoustic performance. With our extensive simulation capabilities, we can predict the effect that our solutions will have on the component, enabling designers to create quieter products.

Acoustic Sealants

About

Reliably sealing the body cavities at key locations in the vehicle results in an improvement in overall acoustic performance and a quieter, more pleasant cabin environment. Our acoustic sealant portfolio is formulated with varying levels of volumetric expansion, density and cell structure designed to minimize the amount of exterior noise entering the interior of a vehicle. Typically, sealants are coupled with various barrier materials such as metal or thermoplastics, which enhance sound transmission loss characteristics. Parts can be processed by injection molding to produce three-dimensional shapes, profile extruded or die cut.

L&L’s acoustic products are usually installed in the body shop prior to the e-coat process. After the e-coat has been applied to the body structure, our heat-activated sealants expand during the e-coat bake cycle so that the entire cavity is completely, reliably, and durably sealed.
