Publication number: 20140179864Abstract: Provided are: a powdered material for slush molding; and a manufacturing process therefor. The powdered material is less odorous, exhibits excellent powder fluidity, and does not suffer from troubles resulting from the sliding-down or agglomeration of a pigment even when the resin particles have been pigmented on the surfaces thereof. Thus, the powdered material ensures high productivity. The powdered material is a powdered polyurethane urea resin composition which comprises (D) a polyurethane urea resin that has a total content of bimolecular condensate of acetone, bimolecular condensate of methyl ethyl ketone, and bimolecular condensate of methyl isobutyl ketone of 1,000 ppm or less and (N) an additive, wherein the polyurethane urea resin (D) takes the form of thermoplastic polyurethane urea resin particles (P) that have a volume-mean particle diameter of 20 to 500 ?m and that have protrusions and recesses on the surfaces.Type: ApplicationFiled: July 30, 2012Publication date: June 26, 2014Applicant: SANYO CHEMICAL INDUSTRIES, LTDInventors: Koichi Saito, Ko Kawasaki, Kakuhiro Kawaguchi, Yasuhiro Tsudo
