Abstract: A method of functionalizing reclaimed elastomer material is described. The method involves subjecting particles of the reclaimed elastomer material to shear at temperatures less than 100° C. such that inter-chain bonds of the reclaimed elastomer material are cleaved wherein the particles of the reclaimed elastomer material have a size of 60 mesh or smaller. The reclaimed elastomer material can be subjected to shear in the presence of a modifier which selectively promotes the cleavage of inter-chain bonds in the reclaimed elastomer material. A functionalized reclaimed elastomer material made by a method as described above and an elastomer compound which comprises the functionalized reclaimed elastomer material are also described.

Abstract: This invention relates to certain rubber formulations which exhibit a low level of hysteresis which are comprised of a chemically functionalized renewed rubber and virgin solution styrene-butadiene rubber. These rubber formulations are loaded with a reinforcing silica. The rubber formulations of this invention can be utilized in making rubber products such as, tires, tracks, and conveyor belts which will promote energy savings by virtue of their low hysteretic properties. The present invention more specifically discloses a rubber composition which is comprised of (1) a solution styrene-butadiene rubber; (2) a functionalized renewed rubber composition which is comprised of an elastomeric polymer and a stabilizer; wherein the rubber composition has a crosslink density which is within the range of 0.05 to 2.0×10−5 mole/g, and wherein the rubber composition has a solubility fraction of less than 90 percent; and (3) a reinforcing filler including reinforcing silica.

Abstract: Elastomer compositions comprising uncured elastomer and reclaimed elastomer are described. In one embodiment, the compositions comprise reclaimed elastomer material (micronized rubber powder) of broad particle size distribution, which is less expensive than traditional reclaimed elastomer material with narrow particle size distribution. Further, compositions comprising reclaimed elastomer materials with broad particle size distribution perform comparably to those comprising reclaimed elastomer materials with narrow particle size distribution. In other embodiments, the compositions comprise both vulcanized and devulcanized elastomer materials. Advantageously, by using a combination of vulcanized and devulcanized material, it is possible to incorporate a greater percentage by weight of reclaimed material in to an elastomer composition, thus providing additional cost savings while maintaining high levels of mechanical properties. Further, the use of the reclaimed material reduces landfill waste resulting in a more environmentally friendly product.

Abstract: Systems, methods, and apparatuses for manufacturing micronized powder. The systems, methods, and apparatuses comprise pre-grinding processing, cryogenic freezing, and grinding of infeed material and warming, ferrous metal and fiber removal, accumulation, screening, and storage of micronized powder. Generally, the warming may involve recirculation of micronized powder through the warming apparatus. Further, the accumulation may permit the grinding and screening to occur at their respectively optimal rates, and the fiber removal, via use of a vibrating screener, may increase the purity of the micronized powder. In one embodiment, the micronized powder comprises micronized rubber powder (“MRP”).
