  • Sound-deadening filled thermoplastic polyolefin composition
    Patent number: 8912271
    Abstract: The present invention relates to filled thermoplastic polyolefin compositions useful e.g., as sound-deadening sheeting for formed automotive applications comprising a propylene polymer having a density equal to or greater than 0.885 g/cm3, one or more linear ethylene polymer and/or substantially linear polymer, a plasticizer, and a filler, preferably calcium carbonate. Said composition demonstrates a good balance of heat properties and stiffness such that it is particularly suitable for sheet extrusion and thermoforming articles therefrom.
