Also provided is a molding die having a molding space corresponding to a shoe member and capable of being used for producing the shoe member by performing the method.

The invention refers to a method for producing expanded polymer pellets, which comprises the following steps: melting a polymer comprising a polyamide; adding at least one blowing agent; expanding the melt through at least one die for producing an expanded polymer; and pelletizing the expanded polymer. The invention further concerns polymer pellets produced with the method as well as their use, e.g. for the production of cushioning elements for sports apparel, such as for producing soles or parts of soles of sports shoes. A further aspect of the invention concerns a method for the manufacture of molded components, comprising loading pellets of an expanded to polymer material into a mold, and connecting the pellets by providing heat energy, wherein the expanded polymer material of the pellets or beads comprises a chain extender. The molded components may be used in broad ranges of application.

The present invention is a molded article containing a polyarylene sulfide resin, a thermoplastic resin other than the polyarylene sulfide resin, and a metal oxide containing at least one of copper or chromium. The polyarylene sulfide resin forms a continuous phase, and a dispersed phase containing the thermoplastic resin and the metal oxide is present in the continuous phase. The present invention is also a polyarylene sulfide resin composition for providing it, a molded article having a roughened surface, a laminate of the molded article and metal, and methods for producing them. According to the present invention, there is provided a molded article that has superior heat resistance of a polyarylene sulfide resin, on which the speed of plating deposition is practical, and with which a laminate with potentially maintained adhesiveness of plating can be obtained and a method for producing it, as well as a polyarylene sulfide resin composition.

A production method for a separated fiber bundle includes at least: [A] a partial separation step for obtaining a partially separated fiber bundle in which separation-processed parts, each separated into a plurality of bundles, and not-separation-processed parts are alternately formed along the lengthwise direction of a fiber bundle comprising a plurality of single fibers; and [B] a cutting step for cutting the not-separation-processed parts of the partially separated fiber bundle formed in the step [A] along the lengthwise direction of the fiber bundle. A separated fiber bundle produced by the method, a fiber-reinforced resin molding material that uses the separated fiber bundle, and a production method for the fiber-reinforced resin molding material.

A roof laminate (10) includes a roof membrane (12, 100, 200, 300) and a protective sheet (14, 114, 214, 314) removably affixed thereto. The surface (20) of the roof membrane (12, 100, 200, 300) can be protected from dirt, scratches and scrapes by a protective sheet (14, 114, 214, 314) which also provides other beneficial attributes that aid an installer. The membrane (12, 100, 200) and the sheet (14, 114, 214) are heat laminated together in the absence of adhesive and tackifiers. Alternatively, the membrane (12, 300) and the sheet (14, 314) are surface treated and then brought into contact with one another in the absence of adhesive and tackifiers. The sheet (14, 114, 214, 314)) may be single layer or include at least a first layer (30) directly secured to a second layer (32). The first layer (30) provides at least one of UV protection, anti-slip, and anti-glare to the roof laminate (10) and so aids the installer in at least one of those respects. The second layer (32) is removably affixed to the roof membrane (12, 100, 200, 300).

Disclosed is a nanosilica-containing thermoplastic hot-melt film having excellent bonding strength, which may be inserted between fabrics to adhere them to each other and may be distributed uniformly on the surfaces of both the fabrics without excessively penetrating into one of the fabrics after melting by heat and pressure during no-sew pressing even if the yarn density of the fabrics is high or low or even if the hole diameter of the fabrics is large or small, thereby increasing the bonding strength between the fabrics.

A fiber-reinforced resin composition includes a polyamide resin and a polyolefin resin, and when one resin between the polyamide resin and the polyolefin resin is set as a first resin, and the other resin is set as a second resin, the composition has a sea-island structure including a continuous phase C consisting of the first resin and a dispersed phase c consisting of the second resin dispersed in the continuous phase C, and in a resin phase separation cross-sectional structure, a total of cross-sectional areas of dispersed phases having a cross-sectional area equal to or smaller than an average cross-sectional area of the reinforcing fiber is 20% or less with respect to a total of cross-sectional areas of all dispersed phases.
