Acoustic Foam / 隔音海绵

The open cell structure of Acoustic Foam allows absorption of airborne sound by dissipating the energy within the cellular network, leading to the highest level of noise reduction. Acoustic foam products in a range of different densities, grades and thicknesses. Whatever type of Acoustic Foam product you want, we are confident that we can manufacture it.

All polyurethane foam can’t be used for acoustic purpose. Since acoustic grade foam is specifically engineered and it has a homogeneous and consistent cell structure it can be effectively used in acoustic applications. We offers a wide range of acoustic insulation products specifically designed to absorb and reduce noise and vibrations.

Acoustical foam’s effectiveness is measured by its Noise Reduction Coefficient, or NRC rating as per ASTM C423 /ISO 354 standard. Noise Reduction Coefficient (NRC) is given by the average value of sound absorption coefficient at 250 Hz, 500 Hz, 1000 Hz and 2000 Hz.

Acoustic foam has good sound absorption properties with a NRC (Noise Reduction Coefficient) value up to 0.8 and hence it is used in many industries like Automotive, Power generation, Construction and HVAC. Acoustic foam can be supplied in various types such as plain sheets, rolls or special shapes like pyramids, wedges, egg tray by using CNC profile cutting machine. They work not only to absorb sounds, but also to enhance the quality of sound and speech in a room.

Since the polyurethane foam is insoluble with a high ignition point and a high-temperature range. It can be incorporated in composites with a self-adhesive backing and it acts as polymeric anti-vibration layer.
