A foam article, such as a cushioning element for an article of footwear, apparel or sporting equipment is provided that comprises a foam component, such as a midsole, having a number of beneficial physical characteristics. The cushioning element is a low-density foamed component with a surface skin that encases the remaining foam volume. The cushioning element has a number of foam volumes, arranged to achieve a more consistent foam component. Additionally, the cushioning element includes a series of concentric ridges extending radially outwardly from injection gate vestige locations, and a number of striation bands near the perimeter of the cushioning element. The location of the gate vestiges can be beneficially arranged to produce intersecting flow boundaries that are located away from key strain areas of the cushioning element. The cushioning element is more environmentally-friendly, requiring less energy to produce while still providing acceptable energy return and low density.

The present invention aims to provide a method for improving the fluidity of a crystal nucleating agent for polyolefin resins without impairing other properties, and a polyolefin resin composition containing the crystal nucleating agent with improved fluidity and having excellent properties including transparency, and a molded article thereof. Adjustment to specific characteristics can improve the fluidity of a crystal nucleating agent for polyolefin resins, and the use of such a crystal nucleating agent having specific characteristics remarkably improves the workability during molding processing and provides a polyolefin resin composition excellent in properties such as transparency, and a molded article thereof.

A curable particulate silicone composition is disclosed. The composition comprises: (A) hot-melt silicone fine particles having a specific reactive functional group; (B) an inorganic filler; and (C) a curing agent. The content of component (B) is in the range of from 87 to 95 vol. % of the total composition. The curable particulate silicone composition provides a cured product having an average linear expansion coefficient of not greater than 15 ppm/° C. in a range of from 25° C. to 200° C. The curable particulate silicone composition provides a cured product having a very low average linear expansion coefficient over a wide temperature range when cured and is particularly suitable for overmold molding and the like.

An object is to manufacture molded bodies having a small variation among products even if the mixture amount of a metal powder is increased when molding is performed by directly introducing not only a metal powder but also a powdered resin into an injection molding machine.

In a metal powder mixed resin molded body manufacturing method for manufacturing a molded body by kneading a molding material including a metal powder, a thermoplastic resin powder, and an additive agent, molding is performed by an injection molding machine in which a molding screw is arranged. The molding screw of the injection molding machine includes a feeding portion, a compressing portion, and a metering portion that are continuously and integrally provided, the feeding portion and the compressing portion are constituted by an one-line spiral flight, the flight of the compressing portion includes a plurality of sub-flights that extend in a spiral manner in a screw axis direction and the sub-flights each have a polygonal shape with rounded corner portions, and the sub-flights are arranged such that the corner portions are shifted by a set angle in a circumferential direction about the screw axis, and the metering portion is provided with a plurality of blending/aligning portions each having gear-like protrusions and recesses in a circumferential direction about the screw axis.

A method for manufacturing an electrically conductive composite material includes obtaining a composite material which includes a thermoplastic matrix and short carbon fibers and is free of carbon nanotubes, preheating a furnace until a predetermined target temperature is reached, inserting the composite material into the preheated furnace once the target temperature has been reached, and heating the composite material in the furnace at the predetermined target temperature which is kept constant for a predetermined duration.

Provided are a polyamide resin having high crystallinity, a high glass transition temperature, and a low mass loss rate, and a polyamide resin composition and a molded article in which the polyamide resin is used. The polyamide resin includes a diamine-derived structural unit and a dicarboxylic acid-derived structural unit, in which 50 mol % or more of the diamine-derived structural units are structural unit derived from p-benzenediethanamine, and of the dicarboxylic acid-derived structural units, from not less than 20 mol % to less than 95 mol % are structural units derived from an aromatic dicarboxylic acid and from more than 5 mol % to not more than 80 mol % are structural units derived from an α,ω-linear aliphatic dicarboxylic acid having from 4 to 15 carbons.
