First, product characteristics introduced:
The D-803-Z damping rubber plate is a high performance free layer damping material, and its structural loss factor is more than 0.2 in the composite structure of the substrate: damping plate = 1:3, 50 ~ 400Hz frequency range. In a certain structural application, the self-noise is reduced by 5.3dB and the target intensity is reduced by 6.5dB. The vibration and noise reduction performance of this product in the cabin interior and exterior, railway locomotives and other fields has been fully verified.
