    摘要： The present invention relates to a polypropylene-based resin composition including: (A) a polypropylene resin in an amount of about 40 to 90 wt %, (B) a metal hydroxide in an amount of about 1 to about 25 wt %, (C) an inorganic filler in an amount of about 5 to about 15 wt %, and (D) a polyolefin-based elastomer in an amount of about 0 to about 20 wt %, and a method for manufacturing the polypropylene-based resin composition.Accordingly, the polypropylene-based resin composition may be applied widely to a molded product of interior or exterior parts of a vehicle because a polypropylene resin composition containing a metal hydroxide may be used to manufacture interior and exterior products of a vehicle, thereby achieving weight reduction due to excellent foaming quality during the foaming injection and improved mechanical properties.

    摘要： A method of manufacturing a resin foam includes dissolving a blowing agent into a mixture of a resin C and a resin D having a difference of solubility with respect to the blowing agent in an amount of more than 0% and less than 5%; subjecting the mixture to heat-melting for extrusion; and evaporating the blowing agent such that the resin foam has a porosity (X) of not less than 80%, a cell (L) with a cell diameter of not less than 1 μm and not more than 1000 μm, and a cell (S) with a cell diameter of not less than 0.01 μm and less than 1 μm, in which two peaks are present in cell diameter distribution, one peak thereof being present in not less than 10 μm and not more than 500 μm and the other peak being present in not less than 0.01 μm and less than 1 μm.

    摘要： A method of manufacturing a blank for a floatation device is disclosed. Polystyrene material is introduced into an extruder and heated. The molten polystyrene is then blown with carbon dioxide to form a polystyrene foam that is extruded into a sizing tunnel to create a desired cross-section for a floatation device blank. The carbon dioxide pressure is preset to provide a resulting polystyrene foam having desired rigidity and density characteristics, and other softening agents may be used to achieve desired rigidity and density characteristics. The extruded polystyrene foam is then cut into blocks of predetermined length, which are then cut and shaped into a desired floatation device blank that may be finished as with conventional blanks.
