摘要： An object of the invention is to provide a blow-molded foam which has homogeneous foamed cells in size, is light in weight, and is excellent in surface smoothness, and a process for producing the same. The invention is directed to a blow-molded foam 1 having a wall portion formed in such a manner that a thermoplastic resin containing a foaming agent mixed therewith is subjected to blow molding. Herein, the wall portion has a closed cell structure in which a plurality of foamed cells are contained. The wall portion has an expansion ratio of not less than 2.0 times. The wall portion has an outer face having a center-line average surface roughness Ra of less than 9.0 μm. The foamed cell has a cell diameter having a standard deviation of less than 40 μm in a thickness direction of the wall portion.

摘要： The invention provides a molded foam molding method capable of obtaining a molded foam in which pinholes may not be formed with ease even when a blow ratio is high and which has a high expansion ratio. The invention also provides a molded foam which includes no pinholes, is reduced in weight, and is excellent in heat insulating property. The molding method includes blending a polypropylene-based resin having an equilibrium compliance from 2.0 to 6.0 (10−3×Pa−1) with a foaming agent and kneading the blend in an extruder. The extruded foamed resin is molded so as to be fit along a mold by a pressurized fluid. Moreover, the molded foam is formed by the method described above, and has an expansion ratio from 1.5 to 5.0 times and an impact strength of not less than 30 kg·cm.

摘要： An object of the invention is to provide a method for manufacturing a molded foam which is lightweight and excellent in strength. According to the invention, a method for manufacturing a molded foam from a foamed parison includes: an extruding step of extruding a resin blend containing a foaming agent and a thermoplastic resin to form a foamed parison; an attaching step of closely attaching facing portions of an inner wall surface of the foamed parison to each other to form a foamed parison laminated body; a mold clamping step of sealing and mold clamping the foamed parison laminated body by clamping the foamed parison laminated body by split mold blocks; and a sucking step of sucking air between the split mold blocks to reduce a pressure between the split mold blocks, after the attaching step and the mold clamping step.
