A foam molding apparatus and a foam molding method thereby are proposed. The foam molding apparatus includes a foaming agent supply unit configured to supply a foaming agent, a molten resin supply unit configured to supply molten resin, a fixed mixing unit configured to produce a foaming resin-critical solution by mixing a foaming agent supplied from the foaming agent supply unit and molten resin supplied from the molten resin supply unit through a rod-shaped body, and a molding unit configured to mold a foam molding product using the foaming resin-critical solution supplied from the fixed mixing unit. Accordingly, it is possible to produce a foaming resin-critical solution by uniformly mixing a large amount of high-viscosity gel-state molten resin and a high-pressure compressed and low-viscosity foaming agent, using high-strength multiple channels.

It is provided a WPC extrusion profile comprising a WPC material, in which plant fibers are embedded in a plastic matrix, wherein the WPC material has a content of naturally growing plant fibers of between 30 and 75 wt-%, and the WPC extrusion profile includes at least one foam-filled hollow chamber. The at least one hollow chamber of the WPC extrusion profile is completely filled up with a foam, in particular a closed-pore foam. The foam includes or consists of a plastic material of the same type of plastic as the matrix of the WPC material. The foaming is effected by using a physically acting blowing agent, in particular CO.sub.2, wherein the density of the foam is less than 0.4 g/cm.sup.3 and the average cell size of the foam has a mean diameter of less than 0.4 mm.

A method for manufacturing a closure constructed for being inserted and securely retained in a portal-forming neck of a product-retaining container is provided. Such method may include intimately combining a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymers, optionally in combination with other constituent(s) to form a composition, heating the composition to form a melt, extruding or molding a closure precursor from the melt to provide a specified water content range, and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure for a product-retaining container includes a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymer, optionally in combination with other constituent(s).

An inventive transfer roller (1) is made of a foam formed from an electrically conductive rubber composition containing an electrically conductive rubber, a crosslinking component, and a foaming agent including OBSH and 0.25 to 2.5 parts by mass of sodium hydrogen carbonate based on 1 part by mass of OBSH, and has an Asker-C hardness of not lower than 25 degrees and not higher than 35 degrees and an average foam cell diameter of not greater than 120 μm. Therefore, the transfer roller is flexible with a lower rubber hardness, and has smaller foam cell diameters. An inventive production method includes the steps of: forming the electrically conductive rubber composition into a tubular body; and maintaining the tubular body at a temperature of not lower than 120° C. and not higher than 140° C. to foam the rubber by a single-stage foaming process.
