Autoneum has unveiled Hybrid-Acoustics PET - innovation for lighter, quieter and more environment-friendly vehicles. Components made of Hybrid-Acoustics PET use only PET, which is largely obtained from recycled fibres, providing environment-friendly mobility option. The innovation is based on a fibre material that acts both as insulator and absorber.

With Hybrid-Acoustics PET, Autoneum has adapted its textile interior technology Hybrid-Acoustics for use in the engine compartment. The patented innovation is based on a unique fibre material that acts as an insulator and absorber at the same time. Among others, Hybrid-Acoustics PET is used to encapsulate electric motors, thereby reducing noise directly at the source and particularly attenuating high-frequency sounds of the electric drive unit. This key technology accordingly ensures optimum noise protection in the passenger cabin and greater driving comfort.

At the same time, components made of Hybrid-Acoustics PET are of low weight. Compared to conventional insulators, they are up to 40 per cent lighter and thereby contributing to a greater driving range. They are also flameproof and find application as powertrain-mounted insulators for combustion engines thanks to their temperature resistance of up to 180 degree Celsius.

The parts, which consist to a large extent of recycled PET fibres, are produced waste-free and are completely recyclable – an outstanding life cycle assessment compared to equivalent components in the engine bay. Hybrid-Acoustics PET therefore exemplifies Autoneum’s commitment as part of its Advance Sustainability Strategy 2025 to continuously improve the environmental performance of its product portfolio and thus contribute to a resource-efficient mobility.

Starting in spring 2020, e-motor encapsulations made of Hybrid-Acoustics PET are being produced for various new electric models of a Swedish car manufacturer at the company’s Taicang plant in China (Jiangsu province). In addition, Autoneum will supply engine-mounted parts to various French and Japanese vehicle models with combustion engines from its site in Ons-en-Bray, France.
