THERMOPLASTIC ALIPHATIC URETHANE/UREA MOLDING COMPOSITIONS.

摘要

Compositions for forming molded articles, particularly, shells for automotive applications are made up of an aliphatic thermoplastic urethane/urea elastomer and, optionally, one or more copolymers, such as an olefin-containing or styrene containing copolymer. These compositions may be used 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.
