A method for making a low density foamed article includes placing a desired amount of thermoplastic polyurethane foam beads in a cavity of an injection mold and closing the mold; combining in an extruder connected to the mold a molten polymer selected from the group consisting of thermoplastic polyurethane elastomers and thermoplastic ethylene-vinyl acetate copolymers with both a physical or chemical blowing agent other than a supercritical fluid present in an amount up to about 15 wt % based on molten polymer weight and a supercritical fluid that is at least one of about 0.1 to about 5 weight percent of supercritical CO.sub.2 based on molten polymer weight or about 0.1 to about 4 weight percent of supercritical N.sub.2 based on molten polymer weight, to form a mixture and injecting the mixture into the mold and foaming the mixture to form the low density foamed article.

A porosity gradient fibrous preform includes a plurality of fabric-resin layers and a plurality of pore formers. Each fabric-resin layer includes a plurality of fibers and a resin. A volume of the plurality of pore formers sequentially increases from a center of the porosity gradient fibrous preform toward an outer surface of the porosity gradient fibrous preform. The pore formers can be pyrolyzed from the preform to create paths through the porosity gradient fibrous preform for infiltration of a fluid.

A sport helmet for protecting a head of a wearer, such as a hockey, lacrosse or football player. The sport helmet has an outer shell with an internal side and an external side and an inner pad mounted to the internal side of the outer shell for absorbing shocks when the sport helmet is impacted. The inner pad has a core of polymeric cellular material with a body of expanded polymeric microspheres and a molded covering being molded onto the core of polymeric cellular material.

A process for insulating a register box in which the register box has a plurality of side panels arranged in a generally rectangular configuration and a duct opening through a wall that extends across the generally rectangular configuration, in which the process includes flowing an expandable polymeric material toward the plurality of side panels, placing the register box into or onto a support structure, introducing a liner over the flowed expandable polymeric material within the register box, and placing a form onto the liner in the register box so as to shape the expandable polymeric material within the register box. The form and the liner are then removed from the register box.

A method, a device and a computer program for manufacturing a pre-insulated skeleton framing segment for a building to be constructed, wherein an assembly with a hollow space is provided, to which a data carrier is fitted including data from which a quantity of raw materials required for forming a foam insulation layer of a thickness in the hollow space can be determined, which quantity is calculated, and which raw materials are inserted in the hollow space, and foam and harden there during a period.

A device for producing an edging of a flat extended panel has: a molding tool; a material dispenser which is movable in relation to the molding tool, for dispensing a material for the edging, wherein the molding tool has: a first mold body having a holding region for the panel; a second mold body having a holding region for the panel such that the panel is capable of being held by the first mold body and by the second mold body; a third mold body which with the first mold body shares a common contact region, wherein the first mold body, the second mold body, and the third mold body are configured such that they conjointly with the panel surround a space in which the edging is configurable; an access duct to the space, the former being configured between the second mold body and the third mold body.

The invention relates to: composite elements comprising a thermoplastic material and a polyurethane adhering to said thermoplastic material; a method for producing same; and the use thereof.

Compression molded foam articles are provided having a closed cell foam structure comprising a plurality of cells having an anisotropic cell shape. The disclosed compression molded foam articles can be used as components or parts of a variety of articles, including articles of footwear and athletic equipment. Methods are disclosed for making the disclosed compression molded foam articles from a foamed preform having an elastomeric closed cell foam with substantially isotropic cell shape. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

An anti-slip rod-shaped rare-earth-modified polyurethane material, the anti-slip rod shaped rare-earth-modified polyurethane material is formed by mixing and curing a premixed material and isocyanate, the premixed material is prepared by mixing a rod-shaped rare-earth oxide pre-dispersion solution, polyethylene glycol (PEG) 600, glycerol, a catalyst, water, and color paste, and the rod-shaped rare-earth oxide pre-dispersion solution is prepared by mixing PEG400, a dispersant, a defoamer, and rod-shaped rare-earth oxides.
