Our 3M™ Thinsulate™ Acoustic Insulation TC1803 is among our lightest-weight NVH solutions for automotive sound absorption and is ideal for filling irregular spaces. With an internal PP/PE web, an overall thickness of 21 mm and a basis weight of just 185 g/m2, it features excellent compressibility and recovery. A durable, 100% polypropylene scrim reinforces the web on both sides.
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.
Recommended Applications:
- Variable cavity NVH
- Door trim panel
- Door hole seals
- Head liners
- Wheel wells
- Trunk liners
- 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 compared fiberglass, shoddy, felt and PET.
- 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 our 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.
