Each reduced decibel is decisive as external or pass-by noise in particular is increasingly regulated in Europe, Japan, but also in China. From 2024, newly registered vehicles in the European Union will be allowed to generate a maximum of 68 decibels of external noise, a challenge for manufacturers and suppliers alike in light of the current threshold of 72 decibels and already highly acoustically optimized cars. To achieve this substantial noise reduction, Alpha-Liner will make an important contribution.
Wheelhouse outer liners made of Alpha-Liner are easy to clean and robust thanks to the plasticized surface, making them more resistant to stone chipping and ice accumulation in the wheelhouse. Compared to corresponding components made of plastic, Alpha-Liner convinces with a lower weight, ensuring a greater driving range especially for electric vehicles. In addition, the components are produced in a sustainable manner. Production scrap of the wheelhouse outer liners, which are primarily made of recycled PET fibers, can be fully recovered and recycled.
