Noise, Vibration and Harshness Solutions for Chassis and Wheels

Our 3M™ Thinsulate™ Acoustic Insulation is available in a broad range of weights and thicknesses for acoustic absorption. It features a polypropylene/polyethylene (PP/PET) web that combines acoustic absorption with excellent compressibility and recovery, which is ideal 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.

More powerful OEM assemblies do not necessarily mean noisier assemblies. Our 3M™ Friction Shims help answer the demand for maximum power density – enhancing friction to transmit higher loads while enabling lightweight designs. This technology is ideal for steering and chassis designs that meet specifications for weight, torque, power density and efficiency of assembly. 3M™ Friction Shims reliably transmit up to 4X higher torque than conventional systems without requiring modifications to joint design.

Our cross-industry expertise allows 3M to provide advanced material technology to automotive OEM and Tier spaces in the form of 3M™ Glass Bubbles – 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.
