Product Descriptions
NALC sound-absorbing board is a rigid porous sound-absorbing material, and it is common NALC board homosexual, homogeneous material, but higher porosity (porosity of ≥ 80% ), bulk density is smaller (dry bulk density ≤380 kg/ m ³), so that it has a better sound absorption, whether it is in the high frequency area or region can exhibit excellent low-frequency sound absorption, sound-absorbing properties significantly higher than the fiber sound-absorbing material.
