RECYCLED POLYETHYLENE TEREPHTHALATE RESIN COMPOSITION WITH IMPROVED PROCESSABILITY WITHOUT ADDING SEPARATE ADDITIVES, AND A MOLDED PRODUCT THEREOF

摘要

PURPOSE: A recycled polyethylene terephthalate resin composition is provided to not need separate synthetic process like adding additives, etc, and to have excellent thermal properties and processability.;CONSTITUTION: A recycled polyethylene terephthalate resin composition is formed by mixing 0.1-10 parts by weight of polycaprolactone into 100.0 parts by weight of a polyethylene terephthalate resin. The recycled polyethylene terephthalate resin has a pellet shape. The number average molecular weight of the polycaprolactone is 70,000-90,000. The recycled polyethylene terephthalate resin molded product is manufactured by injection molding, extrusion molding, or compression molding the recycled polyethylene terephthalate resin composition.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Injection; (BB) Product; (S10) Recycled PET flake; (S20) Crystallization, removing moisture and drying; (S30) Extrusion(Pellet); (S40) Crystallization, removing moisture and drying; (S50) Mixing polycaprolactone
