    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: A method (100) of cryogenically grinding particles exemplary comprising pre-grinding processing (102), cryogenic freezing (104), grinding (106) and warming (108) of infeed material, ferrous metal and fiber removal (110), accumulation (112), screening (114), and storage (116) 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").

    Abstract: This invention is based upon the discovery that micronized solution styrene-butadiene rubber from postconsumer sources can be included in rubber formulations without severely compromising abrasion resistance. The micronized solution styrene-butadiene rubber utilized in the rubber formulations of this invention can be made by cryogenic grinding postconsumer rubber products using conventional procedures. For instance, it can be made by cryogenically grinding a tire tread containing a high level of solution styrene-butadiene rubber. The micronized solution styrene-butadiene rubber can then be blending into desired virgin rubbers and cured without significantly compromising the abrasion resistance of the rubber formulation. The rubber formulation of this invention is comprised of a natural or synthetic rubber and from 1 weight percent to 30 weight percent of a micronized rubber composition containing at least 10 weight percent solution styrene-butadiene rubber and having a particle size of 40 mesh to 200 mesh.

    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.
