Abstract

Filamentos de tereftalato de polietileno (PET) fusionado provenientes de un reactor de policondensación de PET son solidificados, pelletizados, y enfriados solo a una temperatura en la gama de 50ºC a una temperatura cercana a la temperatura Tg del polímero por contacto con agua. Los pellets aun calientes son transportados, opcionalmente seguido por secado para remover agua, a un cristalizador de PET. Evitando el enfriamiento de los pellets amorfos a temperatura ambiente interior con agua y aire frío, se efectúan significativos ahorros de energía.
