摘要
PURPOSE: A micro pellet type thermoplastic polyurethane composition for powder slush molding process and a manufacturing method thereof are provided to enhance mechanical property, light-proof, heat resistance, anti-hydrolysis property, and releasability. CONSTITUTION: A micro pellet type thermoplastic polyurethane composition for powder slush molding process comprises 5-10 weight% of ester-based polyol, 5-10 weight% of ether based polyol, 30-70 weight% of polycarbonate diol, 10-50 weight% of isocyanate, 5-30 weight% of chain extender, and 0.1-5 weight% of light-resistant stabilizer. The ester based polyol is more than one kind which is selected from polycaprolactone polyol, butylene adipate, ethylene adipate, and diethylene diadipate. The ether based polyol is polypropylene glycol, polytetramethylene ether glycol, or a mixture thereof.
