A high polymer resin material is configured into a shoe sole component having a plurality of inwardly extending indentations in one or both of the top and bottom members of the component. The indentations extend into the interval between the members and adjacent to the opposite member to provide support members for the sole component. The sole component can be constructed by molding upper and lower sole component halves wherein the molds are configured to provide indentations in the top and bottom members. The upper and lower sole component halves are then joined to complete the sole component.

A projectile includes: (a) a cured, toughened polymer resin; and (b) a particulate filler distributed through the resin, the filler having a density greater than a density of the resin, wherein the projectile has average density less than the density of lead.

A article of footwear having an upper and a sole structure secured to the upper. At least a portion of the upper includes a substrate layer and a polymer layer. The substrate layer is formed of an air-permeable material, and may be a textile or mesh material. The polymer layer defines a plurality of apertures that expose portions of the substrate layer, and the polymer layer is formed of a polymer material that infiltrates the substrate layer and is thereby secured to the substrate layer. A method of forming the material for the upper includes casting a polymer resin to form the polymer layer.

A well dispersed oxygen scavenging particulate compounded in a polymer matrix. The oxygen scavenging formulation consists of iron powder with a mean particle sizes within 1-25 um and pre-coated with at least one or more activating and acidifying powdered compounds, usually in the form of solid organic and inorganic salts of alkaline and alkaline earth metals such as sodium chloride and sodium bisulfate. The pre-coated iron particulate is dispersed into a polymer resin by using a conventional melt processing method such as twin-screw extrusion. The oxygen scavenging compound is mixed with polymer pellets in the solid state prior to melting. The polymer resin pellets and the coated iron powder are preferably treated with a surfactant in the dry state to help dispersing the iron / salt powder with the resin pellets. The melt extruded compounds are pelletized and kept in the dry state to prevent premature activation.

The present invention is an improved polymeric resin composition comprising units derived from ethylene, from about 20 wt % to about 30 wt % units derived from an α,β-unsaturated carboxylic acid having from 3 to 8 carbons, and optionally an effective amount of at least one additive selected from the group consisting of hindered amine light stabilizers, UV light absorbers, and thermal stabilizers. Resins of the present invention are particularly suitable for preparing transparent laminates useful as glazing elements that provide a greater measure of safety than non-laminated glazing elements.

A composite material, the composite material comprising at least one prepreg, said prepreg comprising at least one polymeric resin and at least one fibrous reinforcement; and conducting particles dispersed in the polymeric resin.

A multilayered insole for footwear comprises a base layer having a first thickness, an intermediate layer having a second thickness and adhered to an upper surface of the base layer, and an upper layer having a third thickness and adhered to a free surface of the intermediate layer. The base and upper layers are both made of a first material formed by foamable polymeric resin compositions. The intermediate layer is made of a second material formed by foamable polymeric resin compositions mixed with recycled foamable polymeric materials. A sum of the first thickness of the base layer and the second thickness of said intermediate layer is larger than 0.5 mm. The third thickness of the upper layer can be from 2 mm to 5 mm.

A broad band antenna including: a body formed of a material having a relative permittivity of 2 to 20, a relative permeability of 1 to 10, and a magnetic loss tangent of 0.001 to 0.2, at a usable frequency; and at least one radiator disposed on the body. The material forming the body may be a composite material formed of a polymer resin mixed with a magnetic powder. The composite material may contain the magnetic powder by 90 wt % with respect to a total weight.

The invention discloses a dual-curing coating. The coating contains ultraviolet curing resin monomers, a low polymer, a photo-initiator, polymer resins, an adjuvant and an organic solvent. In the invention, the dual-curing coating is prepared by synergistic copolymerization of an ultraviolet curing coating system and a solvent-based polymer system. The preparation method of the coating comprises the following steps: firstly thermocuring, and then processing information layers and photocuring at the same time; or firstly photocuring, then processing the information layers, and finally heating with an oven or infrared-heating for further cross-linking curing. Therefore, the dual-curing coating has better comprehensive performances such as fast curing speed, small film-coating cure shrinkage and high crosslinking density so as to achieve the characteristics of chemical corrosion resistance, strong wear resistance, strong high temperature resistance, excellent flexibitity, excellent adhesive force and the like; and the coating can be used for laser anti-counterfeit marks of plastics, cosmetic preparations, ceramic materials, glass, paper, leather, wooden products and metal products as well as production of pigment preparations and the like.

High radiopacity is achieved in a polymeric marker by combining a polymeric resin, a powdered radiopaque agent having uniformly shaped particles of a specific particle size distribution and a wetting agent. The method to produce the marker calls for the blending and pelletization of these materials followed by extrusion onto support beading. The resulting supported tubing is subsequently cut to length with the beading still in place. After ejection of the beading remnant the marker is slipped into place on the device to be marked and attached by melt bonding. Marking of a guidewire allows lesions to be measured while the marking of balloon catheters allow the balloon to be properly positioned relative to a lesion.

The present application is directed to methods for preparation of carbon materials. The carbon materials comprise enhanced electrochemical properties and find utility in any number of electrical devices, for example, as electrode material in ultracapacitors or batteries.

Systems for bone fracture repair are disclosed. One system includes a biocompatible putty that may be packed about a bone fracture to provide full loadbearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration and degrade over time to harmless 5 resorbable byproducts. Fixation devices for contacting an endosteal wall of an intramedullary (IM) canal of a fractured bone are also disclosed. One such fixation device includes a woven elongated structure fabricated from resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven 10 structure to be radially compressed and delivered to the IM canal using an insertion tube. When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.
