ABSTRACT:
A process for preparing extremely small RPET particles comprises proving a quantity of RPET flakes, increasing the crystallinity of the RPET flakes, separating a portion of the RPET flakes having the lowest particle density from the remainder of the RPET flakes, and comminuting the remaining RPET flakes, to prepare RPET particles having an average mean particle size less than 500 microns.
