Optimum protection against tyre noise


A lightweight polyethylene terephthalate fibre-based nonwoven wheel arch liner that absorbs tyre noise has been launched by Autoneum.

The acoustic absorption of the new Alpha-Liner compression-mouldable liner can be tailored to specific vehicle models. This is achieved by changing the porosity of a thin plastic coating that is applied to the liner on its tyre-facing side.
