In the conventional vibration-damping and sound-insulating sheets mentioned above, rubber or asphalt is used as a binder (caking material), but the aggregates include iron sand, iron powder, asbestos, glass wool, rock wool,
Because fiber waste is used, the cost of the aggregate is high, and since it is still formed into a plate shape, its adhesion to walls is weak, and it also has poor mechanical strength, flame retardancy, heat resistance,
There were problems with chemical resistance, etc.
