    Our 3M™ Thinsulate™ Acoustic Insulation TAI2799 is engineered specifically for automotive sound absorption in a thin, very lightweight mat material. With an overall thickness of just 13 mm and a basis weight of 165 g/m2, this material features excellent compressibility and recovery. It is suitable for applications requiring very light weights, low densities and tight tolerances.

    Designed for Automotive Acoustic Performance in Narrow Spaces
    Part of the TAI family of acoustic absorbers for automotive OEM, 3M™ Thinsulate™ Acoustic Insulation TAI2799 is a thin, light, very low density (12.7 kg/m3) mat insulation and an excellent NVH material for applications where noise and mass reduction are major goals. Its internal web features thick and thin fibers and is designed specifically to absorb vibration and help reduce unwanted noise from traveling throughout vehicles. This thin 13 mm mat is excellent for sound reduction in narrow spaces and other applications where very tight tolerances are specified.

    Built for Lasting Noise Absorption
    The internal web of the product is composed of a combination of polyester (PE) and polypropylene (PP) fibers. The PP fibers are extremely fine, allowing for high-energy absorption without adding weight. The thicker PE fibers add loft, strength and stability to the web.

    Properties of 3M™ Thinsulate™ Acoustic Insulation TAI2799
    This acoustic insulation mat material has a caliper of 13 mm and a basis weight of 165 gm/m2.

    Compressible and Conformable for a Range of Applications
    Thinsulate Acoustic Insulation TAI2799 is designed for excellent compressibility and recovery. This is ideal for application to vertical surfaces in vehicle cabins, such as inside door panels and for stuffing pillars. Its light weight also makes it effective for non-load bearing horizontal surfaces, such as package trays, luggage compartments and in combination with headliners, for extremely consistent noise absorption throughout the application.

    Thinsulate Acoustic Insulation TAI2799 can be processed by conventional techniques such as die cutting. It attaches easily using ultrasonic welding, hot melt adhesive or mechanical fasteners.

    Recommended Applications:

    • Narrow spaces with tight tolerances, such as headliners
    • Instrument panels and other areas where contact can inhibit proper sensor operation
    • Applications requiring proper operation of seat belt and other mechanisms
    • Applications requiring proper airflow or pressure release
    • Vehicle pillars
    • Instrument panels
    • Parcel trays

    Reasons Why Automotive Manufacturers Choose 3M™ Thinsulate™ Acoustic Insulation

    • Quieter Vehicles. Provides highly efficient acoustic absorption, particularly in middle- to high-frequency ranges.

    • Lighter Vehicles. Thinsulate acoustic insulation products are made from lightweight polyester and polypropylene non-woven fibers. 

    • Easy to Install. Lightweight and easy to handle, these fiber materials are non-irritating and won’t dust or leave residue on the skin for easier installation without special clothing or safety equipment.

    • Mold, Mildew and Moisture Resistant. Install just the insulation – there’s no need for an additional waterproof layer during application. Thinsulate acoustic insulation is also resistant to mildew growth, reducing the risk of offensive odors. 

    • Efficient Assembly. Attach acoustic insulation using a variety of methods including ultrasonic welding, double-sided tape or mechanical clips.

    • Manufacturing Support. Thinsulate acoustic insulation is supported by a global network of 3M experts. Custom die cutting services are available.

    The Science Behind How Thinsulate Acoustic Insulation Absorbs Noise
    All sound is transmitted through the air as waves. These acoustic waves oscillate at differing frequencies. When oscillating waves contact the fine fibers of Thinsulate acoustic insulation, the resulting friction turns their acoustic energy into heat. The heat irreversibly dissipates and reduces sound. As a result, Thinsulate acoustic insulation applied to automotive interiors reduces interior noise for a quieter, more comfortable ride.
