Sound-Absorbing Foam

APPLICATION SCENARIOS

1. Inner motor compartment walls – reduce the transmission of operational noise

2. Inside the housing – absorb resonance noise and enhance quiet performance

3. Within air ducts – minimize airflow noise

4. Packaging liners – reduce noise caused by vibrations during transportation

Product Description

This product series is manufactured using open-cell polyurethane foam technology, featuring a high open-cell rate (≥98%) and excellent acoustic attenuation performance. While maintaining airflow, it effectively suppresses both structural and airflow-related noise. With outstanding temperature resistance (-40℃ to 120℃) and long-term aging durability, it is suitable for a wide range of electroacoustic noise reduction and energy-absorbing cushioning applications. Customizable in dimensions and acoustic parameters to meet specific needs, offering system-level acoustic solutions.

PRODUCT FUNCTION

The ultra-high open-cell structure delivers broad-spectrum sound absorption, with particularly effective attenuation of high-frequency noise (5–10dB).

Lightweight and resilient, it offers cushioning and protective functions to safeguard equipment from vibration and impact.

The material maintains stable performance across high and low temperatures—resistant to cracking and powdering—making it suitable for various industrial and outdoor environments.

Its low compression set ensures long-term structural integrity and sound-absorbing performance under repeated compression use.
