  • Patent number: 8399574
    Abstract: The present invention provides a resin powder composition for slush molding which can give slush molded articles with more excellent hydrolysis resistance. The present invention relates to a resin powder composition for slush molding which is characterized by comprising as the main component a thermoplastic polyurethane resin powder, preferably a thermoplastic polyurethane elastomer powder, and containing a polycarbodiimide prepared by polymerizing tetramethylxylylene diisocyanate, alkoxy terminated one having a number average molecular weight of 500 to 30,000.

  • Patent number: 8034883
    Abstract: A powdered resin composition for slush molding comprising a thermoplastic polyurethane resin powder (B) as the main component and a fine particle powder (A) of a vinyl type copolymer comprising a copolymer of a monomer (a01) having one vinyl group such as methyl methacrylate and a monomer (a02) having two or more vinyl groups such as ethylene glycol dimethacrylate and having a cross-linked structure; or a fine particle powder (E) of a vinyl type copolymer comprising the (a01) and a monomer (a03) having one or more vinyl groups and one or more functional groups other than a vinyl group such as hydroxyethyl (meth)acrylate and having a cross-linked structure. The fine particle powder is a powder flowability improver which does not cause die stains and the powdered resin composition for slush molding containing the fine powder do not cause staining of molds.

  • Patent number: 7405257
    Abstract: The present invention provides a material for slush molding which is improved in melt properties during slush molding and is excellent in heat resistance, the material being made up of a thermoplastic polyurethane resin (A) the difference between the softening starting temperature (STi) and the softening ending temperature by TMA being from 0 to 30° C., and STi being 135 to 200° C. The resin (A) has a hard segment with an Mn of 200 to 2000 comprising a diisocyanate having a symmetrical structure, a low molecular-weight diamine having a symmetrical structure, and/or a low molecular-weight diol, the content of which being from 5 to 50 wt %, and a soft segment making up of a high molecular-weight diol with an Mn of 500 to 5000, with the aromatic content being 35 wt % or less and the aromatic ring content x and the urea group content y satisfying ?0.1x+2.5?y??0.1x+6.
