3M™ AU0920 Thinsulate™

3M™ AU0920 Thinsulate™ Acoustic Insulation is an advanced non-woven absorber engineered to reduce interior vehicle noise with minimal weight. Designed for OEMs pursuing lightweighting and acoustic excellence, AU0920 delivers superior sound absorption across middle to high frequencies.

With a caliper of 10 mm and basis weight of 107 g/m², this scrim-backed material is ideal for both structural and airborne noise damping. Its blend of fine polypropylene and polyester fibers transforms sound into heat energy, making it an optimal choice for quiet vehicle design.

Where to Use 3M™ AU0920

3M™ Thinsulate™ AU0920 is versatile and adaptable across many automotive interior and structural applications, including:

  • Door panels

  • Headliners

  • Instrument panels

  • Parcel trays

  • Pillars

  • Trunk liners

  • Dashmats

  • Wheel wells

  • Underbody & underfloor cavities

For enhanced acoustic comfort, OEMs may also evaluate it for carpet backings and complex cavity areas. For specific NVH design, consult with a 3M Acoustic Solutions Technical Service Engineer.
