LASER-SINTERABLE POWDER AND SHAPED ARTICLE THEREOF |
摘要 |
<p>A resin powder suitable for laser-sintering is provided, which retains properties of styrene resins such as impact resistance and low water absorption and shows sharp decrease of melt viscosity similarly to crystalline resins at a temperature not lower than the glass transition temperature. The laser-sinterable powder is made of a thermoplastic resin composition comprising 10-80 mass% of a crystalline resin (A) with a melting point of 80-250°C and 20-90 mass% of a styrene resin (B), 1 and having a 50% average particle diameter of 10-100 µm. The Component (A) is preferably a polyolefin resin. The Component (B) is preferably a rubber-reinforced styrene resin composition, wherein the rubber component is preferably an ethylene-±-olefin copolymer rubber and/or a hydrogenated product of a diene rubber. The laser-sinterable powder preferably has a melt flow rate of 5-500 g/10 min.</p> |
