Thermal Acoustic Systems

Through science and the power of multiple technologies, 3M provides materials designed to improve heat transfer while maintaining electrical insulation even in components that are traditionally not thermally conductive. This allows you to incorporate lightweight parts made from materials such as thermoplastics, elastomers and thermoset resins. We also provide 3M™ Nextel™ Ceramic Fibers and Textiles to help protect critical equipment – firewalls, seals, and others – as well as add electrical insulation and structural reinforcement to composites. These lightweight, flexible and extraordinarily durable materials can resist temperatures well over 2300ºF.

Aearo Technologies LLC (Aearo), a 3M company, designs, tests and manufactures innovative, weight-efficient thermal acoustic systems for a broad range of aircraft. A pioneer in cabin comfort, Aearo utilizes a systems approach leveraging extensive in-house capabilities and an innovative portfolio of industry-leading proprietary materials engineered to control typical in-flight airborne noise and structural vibration over a wide range of temperature environments. Aearo’s material catalog includes fuselage damping tiles, bagged fiberglass, acoustic blankets, trim damping, barriers and carpet pad. These materials are available as roll/sheet goods or cut part kits, many of which hold Parts Manufacturer Approval (PMA). Aearo holds Supplemental Type Certificates (STC) for thermal acoustic kits covering a broad range of business aircraft granted by both the FAA and EASA which are available shortly after ordering, reduce installation time and deliver world class performance.
