Die-cut adhesive parts for acoustic protection of vehicles

Die-cut adhesive acoustic protection parts designed by Adhex with the technical teams of the car manufacturers ensure both acoustic insulation and sound absorption. The research and development on the mass per area of the parts will guarantee the insulation of the vehicle: it is then a question of putting in place low thickness but high density films. To improve noise absorption, we use adapted materials such as EPDM cellular rubber (ethylene-propylene-diene monomer), open or closed cell foams, cotton felts or polyester or polypropylene fibers. The aim is to meet, with tailor-made technologies, the specific needs of each car manufacturer. The combination of foam, film and adhesive provides a reliable solution for each case. The manufacturing technique is therefore specific to each part: cutting, lamination, etc…, with a dual objective: precision and lightness of the product, as part of the strategy to make vehicles lighter and reduce environmental impact. Adhex die-cut adhesive parts thus contribute to reduce the noise perceived by users, whether it is noise related to the use of the car (engine, door slamming, vibrations or rubbing…) or noises from outside (aero, rain…).
