摘要:
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.
