IMPROVED METHOD FOR TREATING RECYCLED POLYETHYLENE TEREPHTHALATE

摘要

A process for treating RPET flakes comprises providing a quantity of RPET flakes, comminuting the RPET flakes to prepare RPET particles having an average mean particle size less than about 300 microns, and treating the RPE T particles utilizing a low energy process selected from the group consisting of simultaneously melting and mixing the RPET particles by means of a low energ y melting device to prepare an RPET melt, and thermally treating the RPET particles to dry or crystallize the RPET particles.
