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.
L'invention concerne un procédé de préparation de particules extrêmement petites (RPET) consistant à produire une quantité de flocons RPET, à augmenter la cristallinité de ces flocons, à séparer une partie des flocons possédant une densité particulaire inférieure à ceux restant, et à diviser les flocons RPET restant afin de préparer des particules RPET possédant une dimension particulaire moyenne inférieure à 500 microns.
