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.

This invention relates to rubber reinforcing material with reduced weight, a method for preparing the same, and a tire including the same. According to this invention, there is provided a rubber reinforcing material that has a thin thickness and light weight, and yet has excellent durability. The reinforcing material not only reduces the weight of a tire, but also enables realization of improved rolling resistance.

Disclosed herein are polysaccharide-elastomer masterbatch compositions and processes for preparing the masterbatch compositions. One method comprises a step of a) mixing i) an aqueous polysaccharide dispersion, or ii) a basic aqueous polysaccharide solution, with a rubber latex solution containing a rubber component to form a mixture. The method further comprises the steps of: b) coagulating the mixture obtained in step a) to produce a coagulated mass; and c) drying the coagulated mass obtained in step b). The masterbatch compositions are useful in preparing rubber-containing articles.

A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce at least one of six different materials, wherein each type of material may be configured as a thermosetting elastomer that is crosslinked with ß-hydroxyester linkages. The materials may be configured as a leather-like material, a foam material, a molded elastomer, a coating, an adhesive, and/or a rigid or semi-rigid material. Illustrative articles made from any combination of the six materials may be recycled using a mechano-chemical process to de-crosslink the thermosetting elastomer.

A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.
