Asahi Kasei's rigid sound-absorbing foamed products

Asahi Kasei's rigid sound-absorbing foamed products

Asahi Kasei has developed a material made of foamed polyamide hollow beads of 2 mm to 3 mm in diameter. Taking advantage of its hardness and high heat resistance, the company is proposing the material as a component for engine compartment peripherals. The material, which is less than two centimeters thick and is combined with the company's non-woven fabric "Precise," has twice the sound-absorbing property at 1,000 Hz compared to a melamine foam material of the same thickness. In addition to preventing the transmission of sound, the material can also reduce the reflection of sound inside the container when it is processed into a container and the source of sound is placed inside.
