Process for preparing value-added RPET-containing polymer blend component

摘要

Disclosed is a process for preparing a value-added recycled polyethylene terephthalate (RPET) polymer blend component, directed to combining post-consumer polyethylene terephthalate and a specialty additive, to produce a polymer blend component that is useful and desirable for the manufacture of new products. The process 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 a specialty additive to the RPET particles and mixing the RPET particles and specialty additive to prepare a homogenous blend.
