Abstract
Compositions for forming molded articles, particularly, shells for automotive applications are made up of melt blends of an aliphatic thermoplastic urethane elastomer and one or more polyolefin-based modifiers. These compositions may be blended to form a powder, pellets, microspheres or minibeads which may then be cast to form air bag door and instrument panel cover skins which may meet automotive deployment and weathering requirements.
