ABSTRACT:
The noise insulating material comprises a binder resin, sound barrier filler, liquid rubber and fire-resistant fiber. The incorporation of fire-resistant fiber in the binder resin reinforces the resin matrix to prevent melting and shedding of the binder resin upon exposure to a flame. Being qualified as a quasi-incombustible material, this noise insulating material can be used in a broad range of applications.
