Abstract: 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.

Abstract: The present invention relates to articles comprising crosslinked polymer network comprising thioether crosslinks and process of making and using same. Such thiol-ene crosslinking reactions not only make the isocyanate crosslinking reaction unnecessary, but they also improve the article's strength due to chemical crosslinking between the article's resin layers, and reduce or eliminate post curing. Thus resulting in a sufficiently cured article in a much shorter time.

Abstract: To provide a rubber composition excellent in elasticity and low loss property.
A rubber composition comprising 100 parts by weight of a chloroprene rubber and from 1.2 to 3.0 parts by weight of cellulose nanofibers, characterized in that a vulcanized sheet obtained by vulcanizing the rubber composition has a 100% tensile stress (M100) increased by 1.5 MPa or more per part by weight of the cellulose nanofibers added, where the increase of M100 is calculated by subtracting M100 of a vulcanized sheet containing no cellulose nanofibers from M100 of the vulcanized sheet containing the cellulose nanofibers, and dividing the difference by the amount of the cellulose nanofibers contained.
