    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”).

    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: Curable elastomer compositions are described which include particles of reclaimed elastomeric material having a particle size of 60 mesh or smaller, sulfur and one or more accelerators, wherein the ratio by weight of the one or more accelerators to sulfur in the composition is at least 1:1. Curable styrene butadiene rubber (SBR) elastomer compositions are also described which include reclaimed elastomeric material, sulfur and one or more accelerators, wherein the ratio by weight of the one or more accelerators to sulfur in the composition is at least 1:1. The cured elastomeric compositions exhibit improved physical properties compared to elastomer compositions containing reclaim material which employ conventional high sulfur cure systems.

    Abstract: 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.

    Abstract: Methods for making elastomer compounds are described. The compounds include reclaimed vulcanized elastomer materials such as micronized rubber powders (MRP). The elastomeric compositions exhibit lower tensile strength variability. As described herein, shorter mixing times can be used to achieve the same minimum tensile strength as composition containing no reclaimed material. The elastomeric compositions may include various proportions of reclaimed vulcanized elastomer materials. A rubber compound is also described which comprises reclaimed material and which has a minimum tensile strength equal to or higher than a predetermined minimum tensile strength associated with a compound containing no reclaimed material. The rubber compound is manufactured with a reduced mixing time compared to that of the compound with no MRP.
