The sound absorption performance of the rubber foam insulation board will have a lot of direct relations with the physical structure of the product itself. Because the rubber foam insulation board product is foamed tightly and the surface layer is elastic, it has a good effect on reducing the external sound. However, the sound that can be reduced during the actual use of the rubber-plastic insulation board and many environmental factors determine whether it is reduced or isolated. For example, their thickness and density and the flow resistance of air have a great influence on them. Air flow resistance is usually the ratio of the pressure of the air on both sides of the material per unit thickness and the flow rate between the air on both sides. It will also affect the sound absorption efficiency of the rubber foam insulation board. If the flow resistance is too small, this indicates that the entire material is very sparse. In the process of air vibration, it is particularly easy to pass through such a material, and their performance There will be a decline.
