Taking weight out of the vehicle is a big challenge. It’s also a big part of our scientific curiosity as we develop new automotive lightweighting solutions. Take a look at what we’ve delivered so far. If you don’t see your solution here, let’s talk.
Our 3M™ Thinsulate™ Acoustic Insulation is available in a broad range of options for acoustic absorption in various weights and thicknesses. It features a polypropylene/polyethylene terephthalate (PP/PET) web that combines acoustic absorption with excellent compressibility and recovery, which is great for cavity filling and acoustic insulation. It can be attached using methods including ultrasonic welding and double-sided tape as alternatives to mechanical clips. This hydrophobic material can be processed with sealed edges, making it uniquely suited for exterior applications such as wheel arch liners where resistance to water and other contaminants is critical.
A simple method becomes even more effective for adding emblems and other differentiating visual elements to your designs. These thin, conformable acrylic foam tapes (AFT) feature adhesives formulated for attachment to automotive substrates, as well as treated liners for smooth, efficient tape application.
3M™ Acrylic Foam Tapes and Acrylic PlusTapes are ideal for eliminating the use of mechanical fasteners in automotive exterior applications. Often used for sensor bonding, these tapes can replace ultrasonic welding. The conformable, viscoelastic foam cores provide excellent stress relaxation under high application loads and maintain tight bond lines under normal conditions. These tapes have been developed specifically for attaching exterior trim and other parts to automotive paint surfaces.
This range of 3M™ Acrylic Foam Tapes allows for the installation of exterior brackets and trim without heavier mechanical fasteners or ultrasonic welding – and without the time, expense and added process times associated with adhesion promoters. All tapes feature viscoelastic acrylic foam cores for stress relaxation under high application loads and tight bond line aesthetics. These double-sided adhesives are formulated for specific substrates and for robust performance – even on complex contours and difficult automotive surfaces.
Our cross-industry expertise allows 3M to provide advanced material technology to automotive OEMs and Tier suppliers. 3M™ Glass Bubbles are microscopic, hollow glass microspheres that feature an extremely high strength-to-density ratio. This material is supplied as a polymer additive that can replace heavier materials without sacrificing the integrity of the component. In fact, it can reduce density in plastics, composites and coatings by up to 50%. 3M™ Glass Bubbles can be used in injection molded parts and sheet molded composites (SMCs), ideal for lightweight door panels hoods and trunk lids. They are also commonly used in seam sealing and underbody coatings.
