Abstract
The present invention relates to a method for converting an elastomer to a decreased size in a grinding apparatus is disclosed. The method includes optionally soaking the elastomer in a first additive. The method further includes reducing the size of the elastomer to form at least one elastomer particle of a first size. The method also includes optionally removing impurities from the elastomer. Further, the method includes adding a carrier to the elastomer particle to form an elastomer slurry. Also, the method includes providing a second additive to the slurry. In addition, the method includes converting the elastomer particle to a second size, the second size being less than the first size. The method also includes recovering the elastomer particle of the second size. The invention also relates to novel ground elastomers and methods for their use.
