Title:
POLYURETHANE RESIN BASED SLUSH MOLDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2003/085023
Kind Code:
A1
Abstract:
A slush molding material which comprises a polyurethane resin (A) exhibiting a difference between a softening starting temperature and a softening completion temperature as measured by the thermomechanical analysis penetration method of 0 to 30°C and a softening starting temperature of 135 to 200°C, wherein the resin (A) has a hard segment comprising a diisocyanate having a symmetrical structure and a low molecular weight diamine having a symmetrical structure and/or a low molecular weight diol and having a number average molecular weight of 200 to 2000 in a content of 5 to 50 wt %, and has a soft segment comprising a high molecular weight diol having a number average molecular weight of 500 to 5,000, has an aromatic ring content of 35 wt % or less, and has an aromatic ring content of x and a urea group content of y satisfying the formula: -0.1x + 2.5 ≤ y ≤ -0.1x + 6. The slush molding material exhibits improved melting property in slush molding and also is excellent in thermal resistance.
