The present invention provides a stabilising composition, comprising: a) a first phenolic antioxidant comprising one or more phenolic compounds having the structure of formula (I): ##STR00001##  wherein R.sub.1 is a linear or branched alkyl group having from 12 to 20 carbon atoms; and b) one or more second phenolic antioxidants independently selected from:  a mono-hydroxybenzene having lower steric hindrance than the first phenolic antioxidant;  a di-hydroxybenzene; and/or  a tri-hydroxybenzene.

A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

A process for producing a molded article involves providing a thin-walled, gas-permeable shell; filling the shell with a foamed pelletized material composed of a polymer; and welding the foamed pelletized material to obtain the molded article. Molded articles are obtainable or obtained by such a process, and can be used as a footwear sole, part of a footwear sole, a mattress, a seat cushion, an underlay, a grip, a protective film, a component in automobile interiors and exteriors, a gymnastics mat, a body protector, a trim element in automobile construction, a sound insulator, a vibration damper, a cushion, a bicycle saddle, a toy, a tire or part of a tire, a covering for a track and field surface, a covering for a sports hall or a pathway, a damping layer or a damping core in a sandwich element, or a packaging.

A flexible discontinuous process produces a series of at least two articles containing thermally insulating polyurethane foam from at least three streams (A), (B) and (C). The process involves mixing the at least three streams with different mixing ratios and injecting the mixture into cavities of the articles. A production unit can be used for performing this process.

The present invention relates to a process for the preparation of a coating, a coated substrate, an adhesive, film or sheet, which process comprises the application of a formulation mixture containing a reactive system onto a substrate. According to the invention a low VOC formulation mixture is used, wherein more than 40% of the carbon in the combined amount of the formulation mixture is modern carbon according to ASTM D6866.

Provided is a method of recycling an additively manufactured object into a reusable thermoplastic polymer, which method in some embodiments may include: (a) providing at least one additively manufactured object produced by stereolithography from a dual cure resin, the object comprising (i) a light polymerized polymer, and (ii) a heat polymerized polymer intermixed with said light polymerized polymer; (b) comminuting the object to produce a particulate material therefrom; (c) contacting the particulate material to a polar, aprotic solvent for a time and at a temperature sufficient to extract the heat polymerized polymer from the particulate material into said solvent, leaving residual particulate material comprising said light polymerized polymer in solid form; (d) separating the residual particulate material from said solvent; and then (e) separating the heat polymerized polymer from said solvent to provide a reusable thermoplastic polymer material in solid form.

Improved soles and insoles for shoes, in particular sports shoes, are described. In an aspect, a sole for a shoe, in particular a sports shoe, with at least a first and a second surface region is provided. The first surface region comprises expanded thermoplastic polyurethane (“TPU”). The second surface region is free from expanded TPU.

Provided is a water blocking material prepared by reacting and foaming a starting material composition that contains a polyol, a polyisocyanate, a catalyst, a foaming agent, a foam stabilizer and a crosslinking agent, in which the polyol contains a dimer acid polyol, the content of the dimer acid polyol in the starting material composition is 85% by mass or more of the entire polyol, the polyisocyanate contains a diphenylmethane diisocyanate, the content of the diphenylmethane diisocyanate in the starting material composition is 70 to 85% by mass of the entire polyisocyanate, and the foam stabilizer contains a reactive silicone. The water blocking material is excellent in heat resistance and water blocking performance and is further excellent in flexibility.

In one aspect, compositions are described herein. In some embodiments, a composition comprises a phase change material, a hydrophobic sorption material, and a viscosity modifier. In some embodiments, a composition comprises a foam and a latent heat storage material dispersed in the foam, the latent heat storage material comprising a phase change material and a hydrophobic sorption material.

Materials that exhibit stress-induced porosity, and methods of making and using the same, are described.
