Abstract
A vehicle instrument panel skin comprises residues of a thermoplastic urethane elastomer and a propylene-ethylene copolymer. The thermoplastic urethane elastomer includes a polyol, an organic diisocyanate, an optional chain extender, and an optional hindered amine light stabilizer and a benzotriazole ultraviolet stabilizing agent. A method for forming the instrument panel skin is also provided.

An instrument panel skin comprising:
- residues of a composition having polyol, a chain extender, an organic diisocyanate, and a hindered amine light stabilizer and a benzotriazole ultraviolet stabilizing agent;
- and a propylene-ethylene copolymer;
A method of forming a instrument panel skin, the method comprising:
- a) introducing a urethane-based resin composition into a mold tool, the urethane base resin comprising:
- residues of a composition having polyol, a chain extender, an organic diisocyanate, and a hindered amine light stabilizer and a benzotriazole ultraviolet stabilizing agent;
- and
- a propylene-ethylene copolymer;
- b) heating the urethane based resin composition to a sufficient temperature to form a layer over at least a portion of the mold tool;
- c) pouring out powder from the mold tool;
- d) optionally continuing to heat the mold tool so that all the powder melts;
- and
- e) removing the instrument panel skin from the mold tool.
