Abstract

Unas mejoras en los sistemas de coloración y aditivación del Polietilentereftalato (PET). La novedad, objeto de esta patente, es conseguir, de forma empírica, el cruce de productos habitualmente usados en otras industrias, con los sistemas clásicos de obtención de concentrados para PET, y comprobar su idoneidad en las aplicaciones para fibras, láminas y botellas, observando mejoras sustanciales en su comportamiento, tanto en la dispersión como en la difusión. Analizando las propiedades ecológicas, organolépticas, mecánicas, ópticas, etc. puedo garantizarse que no apareció ningún parámetro que imposibilitara su uso.Some improvements in the systems of coloration and additivation of Polyethylene Terephthalate (PET). The novelty, object of this patent, is to achieve, in an empirical way, the crossing of products commonly used in other industries, with the classic systems of obtaining concentrates for PET, and to check their suitability in applications for fibers, sheets and bottles, observing substantial improvements in their behavior, both in dispersion and diffusion. Analyzing the ecological, organoleptic, mechanical, optical properties, etc. I can guarantee that no parameter appeared that made its use impossible.
