Aliphatic, sinterable, thermoplastic polyurethane molding compositions
摘要:
A light-stable, sinterable particulate thermoplastic molding composition is described. The thermoplastic compositions of the present invention consist essentially of: (i) a resinous blend of, (a) thermoplastic polyurethane, and (b) a member selected from at least one of a number of recited copolymers, e.g., a styrene-acrylonitrile copolymer; (ii) a UV stabilizer; and (iii) an antioxidant. The thermoplastic polyurethane (a) is prepared from an aliphatic or cycloaliphatic diisocyanate. The molding compositions are suitable for the preparation of textured sintered films, e.g., by the powder-slush process, having improved tactile properties that, for example, may be used in the fabrication of vehicle interior trim components and vehicle air bags.
