Flexible foam
One of the advantages of polyurethane foam in the automotive industry is its sound-absorbing properties. Vehicles produce various noises that can be disturbing to passengers. These sounds can be categorized into two types: airborne noises from outside the vehicle or structural noise generated by the vehicle’s internal structures. Since these sounds range between 500 to 2500 Hz, which is a frequency range sensitive to human hearing, they can be particularly bothersome.
Polyurethane foam can absorb sound waves and reduce the noise level inside the car cabin. This foam can be used in various parts of the vehicle, including doors, the roof, and the floor, significantly reducing unwanted noises.
