Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

The invention relates to an elastomeric film-forming composition (a) a carboxylated butadiene-based elastomer, (b) polychlorobutadiene in an amount of less than 30% by weight of the polymer content of the composition, and (c) one or more cross-linking agents. The invention also relates to dipped articles, gloves, methods of manufacture and uses involving the composition.

A heat conductive sheet of the present invention is a heat conductive sheet containing a curing reaction catalyst, wherein a heat conductive uncured composition 2 not containing a curing reaction catalyst is joined to at least one principal surface of the heat conductive sheet 1 containing a curing reaction catalyst. The heat conductive sheet 1 containing a curing reaction catalyst contains the curing reaction catalyst in an amount necessary to cure the heat conductive uncured composition. A mounting method of the present invention includes: joining a heat conductive uncured composition 2 not containing a curing reaction catalyst to at least one principal surface of the heat conductive sheet 1 containing a curing reaction catalyst, and curing the heat conductive uncured composition by diffusion of the curing reaction catalyst contained in the heat conductive sheet 1. Thereby, the heat conductive uncured composition can be joined to the heat conductive sheet immediately before mounting to an electronic component or the like, easily follow the unevenness of a heat generating part and/or heat dissipating part, and cure after mounting.

A multi-layer exercise mat including a first layer including an outer surface and an opposing inner surface, the opposing inner surface of the first layer including a first array of three-dimensional features integral with the first layer; and a second layer including an outer surface and an opposing inner surface, the opposing inner surface of the second layer including a second array of three-dimensional features integral with the second layer. The first and second arrays of three-dimensional features are configured to grip each other to removably secure the inner surface of the first layer to the inner surface of the second layer.
