CELLULAR POLYESTER MADE OF POST-CONSUMER FLAKES AND THE USE OF PRODUCTS MADE THEREOF

摘要

Manufacturing of polyester based expanded materials made mostly of pre-cleaned and compounded post-consumer polyester by increasing the intrinsic viscosity (IV) during an extrusion process is described. By careful selection of processing conditions and parameters, it is possible to obtain low density polyester foam material with good cellular structure and under stable processing conditions.
