Abstract
The present invention relates to novel granules and novel methods for manufacturing such granules. In particular, the invention describes granules formed by the agglomeration of resin wetted powder. When the powder is aerated before applying the resin to the powder, granules that are densely packed and homogeneous throughout are formed through agglomeration conditions. The densely packed granules are free of air bubbles greater than 10 microns in diameter. Such novel granules are useful in the manufacture of fabricated products of superior quality.
