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.

A poured-in-place protective surface, such as can be installed at a playground, includes an impact-attenuation or cushion layer, which comprises a blend of (a) a rubber chunk component made up of granules of reclaimed rubber, the reclaimed rubber being from non-tire sources; (b) a tire buffings component; and (c) a binder. The ratio of rubber chunk component to tire buffings component is selected to be between 1.25:1 and 10:1, and more particularly between 1.25:1 and 5:1.

A method of combining rubbers and plastics when injection molding, and compositions usable in injection molding, are shown and described. Comminuted rubber from waste tires and waste plastics including any of high density polyethylene, polyethylene terephthalate, and polypropylene are combined and heated to melt at least the plastics. In one optional approach, both are melted. Plastics comprise from twenty to eighty percent by weight of the mixture, with rubber accounting for the balance. The mixture may be fortified with bonding, compatibilizing, and strengthening agents. The compositions may be cooled and pelletized for immediate use in injection operations.

PRISM Thermoplastic Rubber (PTR) is a novel, composite rubber material technology principally compounded from EOL, ambient ground, whole tires through the management of a unique process governed by the application of advanced, quantum field physics. The value from this technology is to provide a virgin-material-analog that may be readily integrated at high ratio, into new tire construction using conventional tire chemistry and manufacturing techniques resulting in a sustainable and significant, positive cost-benefit ratio as compared to current tire manufacturing economics.

A flexible pipe for transporting fluids in hydrocarbon production. The flexible pipe includes at least one layer comprised of a thermoplastic vulcanizate (TPV) composition. In one embodiment, the TPV composition further includes a cyclic olefin copolymer present in a range from 0.1 wt % to 30 wt % based upon a total weight of the TPV composition. In another embodiment, the TPV composition further includes a hydrocarbon resin present in a range from 0.1 wt % to 30 wt % based upon a total weight of the TPV composition. In another embodiment, the TPV composition further includes a slip agent present in a range from 0.1 wt % to 30 wt % based upon a total weight of the TPV composition. In another embodiment, the TPV composition further includes a silicon hydride reducing agent compound with at least two Si—H groups. In another embodiment, the TPV composition further includes a polyolefin based compatibilizer. In another embodiment, the TPV composition has an abrasion resistance of 75 mg/1000 cycle or less. In another embodiment, the TPV composition has a CO.sub.2 gas permeability greater than 10 barrers.

Thermoplastic elastomers comprising micronized or pulverized rubber powders are disclosed having physical properties equivalent to those of virgin thermoplastic elastomers. For example, the use of finer mesh MRP (e.g., particles of size that would pass through 40 mesh or smaller) to manufacture thermoplastic elastomers results in thermoplastic elastomers that have physical properties equivalent to those of virgin thermoplastic elastomers. Similarly, the use of a glycidyl functional terpolymer (optionally in combination with trimellitic anhydride or “TMA”) to manufacture thermoplastic elastomers comprising MRP results in thermoplastic elastomers that have physical properties equivalent to those of virgin thermoplastic elastomers. Moreover, the use of styrene-ethylene/butylene-styrene thermoplastic (e.g., “SEBS”) in place of the base polypropylene thermoplastic elastomer to manufacture thermoplastic elastomers comprising MRP also results in thermoplastic elastomers that have physical properties equivalent to those of virgin thermoplastic elastomers.
