Absorbs Noise So That Passengers Ride in Comfort
To make the ride in vehicles more comfortable for passengers, 3M™ Thinsulate™ Acoustic Insulation AU3002 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.
Our AU series of automotive sound insulation is recommended for door panels, headliners, instrument panels, parcel trays, pillars, and trunk liners. Depending on application requirements, 3M™ Thinsulate™ Acoustic Insulation AU3002 may be evaluated for use in the carpet/dashmat, under body, under floor, wheel well and other variable cavity applications. To determine suitability, consult your 3M Acoustic Solutions Technical Service Engineer.
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.
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, re

Very Light Weight for Mass Reduction
Part of our TC family of cavity filling solutions for automotive OEM, 3M™ Thinsulate™ Acoustic Insulation TC1803 has one of the highest acoustic absorption-to-weight ratios of any Thinsulate product. This very low density (8.8 kg/m3) insulation is excellent as an NVH cavity filler for applications where mass reduction is a major goal. Its internal web features thick and thin fibers and is designed specifically to absorb vibration and help reduce unwanted noise from traveling throughout vehicles.
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. The lightweight reinforcing white scrim on both sides is made from 100% polypropylene non-woven fabric for durability.
Properties of 3M™ Thinsulate™ Acoustic Insulation TC1803
This acoustic insulation material has a caliper of 21 mm and a basis weight of just 185 g/m2. Fibers are contained in a single scrim.
Compressible and Conformable for Gap Filling
Thinsulate Acoustic Insulation TC1803 is designed for excellent compressibility and recovery. This is ideal for applications where filling spaces of varying thickness is important, such as door trim panels and body side trim panels. As the insulation conforms, it completely fills even irregular spaces for extremely consistent noise absorption throughout the application. It is most effective as an NVH cavity filler.
Our Thinsulate Acoustic Insulation TC1803 can be processed by conventional techniques such as die cutting. It attaches easily using ultrasonic welding, hot melt adhesive or mechanical fasteners.

Designed for Automotive Acoustic Performance in Narrow Spaces
Part of our TAI family of acoustic absorbers for automotive OEM, 3M™ Thinsulate™ Acoustic Insulation TAI2027 is a very thin, very low density (16.2 kg/m3) mat insulation. It is 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. The lightweight reinforcing white scrim is made from 100% polypropylene non-woven fabric for durability, and is embossed for added durability.
Properties of 3M™Thinsulate™Acoustic Insulation TAI2027
This acoustic insulation mat material has a caliper of 13 mm and a basis weight of 230 gm/m2. Fibers are protected by a single scrim which is embossed for added abrasion resistance during and after installation.
Compressible and Conformable for a Range of Applications
3M™ Thinsulate™ Acoustic Insulation TAI2027 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 properties also make 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.
