3M™ Thinsulate™ Acoustic Insulation SM600L absorbs sounds to provide superior acoustic control in vehicles. Our automotive acoustic insulation can be used for a variety of sound management applications. Thinsulate acoustic insulation has extremely efficient sound absorption properties, allowing OEMs to use only what they need to make a difference in sound abatement.
Absorbs Noise So That Passengers Ride in Comfort To make the ride in vehicles more comfortable for passengers, 3M™ Thinsulate™ Acoustic Insulation SM600L absorbs noise so that it is quieter in the interior of vehicles. Our automotive acoustic insulation is made from a unique combination of fine microfibers that absorb high frequency noise and thicker fibers that provide recovery and loft. It is compressible, lightweight, conformable and can be easily die cut, heat sealed and thermally or sonically bonded to many substrates. How Thinsulate Acoustic Insulation Works Our insulation is a unique non-woven acoustic absorber composed of polyester and polypropylene fibers. The polypropylene fibers are extremely fine, producing a high-energy absorption characteristic with low weight. The polyester fibers are added to strengthen the web, while the scrim protects and contains the fibers. Application Recommendations Our SM series of automotive sound insulation is recommended for instrument panels, parcel trays, pillars, trunk liners and wheel wells. Depending on application requirements, 3M™ Thinsulate™ Acoustic Insulation SM600L may be evaluated for use in the carpet/dashmat, door panels, headliners and other variable cavity applications.
