Patent

CA 2516149

A process for preparing an RPET polymer blend component comprises providing a quantity of RPET flakes, comminuting the RPET flakes to prepare RPET particles having an average mean particle size from about 500 microns to about 5 microns, adding at least one specialty additive to the RPET particles, and mixing the RPET particles and specialty additive, to prepare a homogeneous blend of RPET carrier and specialty additive.

L'invention concerne un procédé de préparation d'un composant de mélange polymère contenant du PET recyclé qui consiste à produire une quantité de flocons de PET recyclé, à fragmenter les flocons de PET recyclé afin de préparer des particules de PET recyclé qui présentent une dimension granulométrique moyenne comprise entre environ 500 microns et environ 5 microns, à ajouter au moins un additif spécial aux particules de PET recyclé et à mélanger les particules de PET recyclé et l'additif spécial afin de préparer un mélange homogène de support de PET recyclé et d'additif spécial.
