Using the new PP+PET bi-component technology, the melt-blown polypropylene fiber has a diameter of 2-6 μm, combined with polyester fiber to form a three-dimensional mesh continuous porous fiber material. Compared with traditional automotive sound-absorbing materials, such as open-cell foam, felt, PET cotton and other materials, the PP+PET bi-component structure of the sound-absorbing material has excellent mid- and high-frequency sound absorption performance, light weight, low thermal conductivity, high temperature resistance, hydrophobicity, environmental protection and other properties.
auto sound insulation material application
The PP+PET bicomponent acoustic material is primarily used in automotive NVH (Noise, Vibration, and Harshness) management. It effectively reduces in-cabin noise while being lightweight, making it ideal for supporting vehicle lightweight design.
