3M™ Thinsulate™ Acoustic Insulation TC2303 is a cavity filling solution for automotive sound insulation applications.

General Description 

3M™ Thinsulate™ Acoustic Insulation TC Series is a cavity filling solution for automotive sound insulation applications. The products are uniquely high performance and low density making them ideal for mass reduction applications. They are readily processed by conventional techniques such as die-cutting, heat sealing, and ultrasonically bonded. Thinsulate TC Series are compressible, providing the ability to fit a wide range of applications where varying thicknesses are highly desired, such as door trim panels and body side trim panels. The products are highly conformation and designed to accommodate the irregular spaces behind trim panels, headliners, and instrument panels. Thinsulate TC Series are products are designed for optimal cavity filling — the products fill voids in pillars, behind trim panels, in headliners, or instrument panels to help reduce unwanted noise.

General Construction 

The web is composed of 50% polyester staple fibres, and 50% polypro-pylene fibres. The polypropylene fibres are extremely fine, producing the high-energy absorption characteristic with the low weight. The polyester fibres are added to strengthen the web. The scrim attached to both sides is a 100% polypropylene non-woven fabric. 

Special Characteristics 

Suitable for applications in vehicle cabin, headliners, trim panels, luggage compartment interiors and exterior applications like bumpers and wheelarch liners. It is conformable to accommodate the irregular spaces behind trim panels. TC2303 fills voids to help reduce unwanted noise from travelling throughout the vehicle. Attaching to trim panels is recommended, preferably using ultrasonic or heat spot welding, but adhesives (double sided pressure sensitive tapes or hot melt) may also be used. It can be processed by conventional techniques such as die-cutting and heat sealing. Not recommended for applications where temperatures will be continuously above 120° C.
