Noise, Vibration and Harshness Sealants

Automakers face the complex challenge of meeting increased consumer expectations for comfort, while integrating lightweight material that can be less effective at blocking or deadening noise. This makes material solutions to reduce noise, vibration and harshness (NVH) more important than ever across the automotive manufacturing process.

Acoustic Sealant Tapes

For automotive manufacturers, noise reduction tapes are not simply material afterthoughts in the production process, but essential components of an automobile. Henkel’s acoustic sealant tapes help block noise from traveling through the smallest gaps between metal sheets to small- to large-sized gaps between metal panels.  

Acoustic Sealing Baffles

Henkel’s acoustic sealing baffles consist of heat-reactive sealers applied to a nylon or steel carrier, which is precisely positioned to ensure the right amount of sealer is applied in exactly the right location.

The sealer material expands with exposure to heat in the paint shop bake ovens, forming a complete seal of the cavity cross sections where they are applied. Ideal for large-sized cavities, greater than 25 mm, Henkel’s acoustic sealing baffles can achieve a variety of expansions from one single material, reducing tooling costs and improving design and manufacturing flexibility.

Sound Damping & Deadening Materials

Sound deadening materials such as sound deadening insulation and automotive acoustic insulation help to reduce noise, vibration and harshness within the vehicle. Henkel’s acoustic sound barrier material includes insulation  specifically designed to deaden external sounds.

Liquid Applied Sound Deadener

Spray on sound deadening materials combine easy and quick application with effective noise reduction in key areas such as vehicle doors, roofs and floor assemblies. Liquid Applied Sound Deadeners contribute to weight reduction by replacing heavier bitumen pads and are applied through spray application for increased precision, speed, and improved cleanliness, while removing the need for tooling or part design.

Anti-Flutter & High Damping Foam Solutions

Henkel’s simulation-based engineering helps ensure our anti-flutter foam and high damping foam technologies achieve maximum automotive sound deadening insulation with minimal use of product. This is particularly important as thinner material is introduced exposing exterior panels, such as vehicle doors and roofs, to unwanted movement from wind resistance.

Anti-flutter foam helps limit the movement of the outer panels, while high damping foam eliminates the need for a bitumen pad and further dampens the movement of the exterior panels. Our ultra-soft anti-flutter material is used to ensure the avoidance of adhesive read-through to improve the overall quality of application.
