  • Sound dampening foam
    Publication number: 20050042437
    Abstract: A closed-cell foam comprises at least about 50 weight percent thermoplastic polymer and from about 5 to about 50 weight parts of particles dispersed in the thermoplastic polymer per 100 weight parts of the thermoplastic polymer. The particles have an average size in the longest dimension of from about 5 to about 300 microns. If the particles are electrically conductive, then the foam has a surface resistivity of at least about 1×106 ohms. The foam is useful in sound dampening applications.
