摘要：NOVELTY - A supercritical carbon dioxide foaming method of polyester comprises drying polyethylene terephthalate, melting, extruding, subjecting extruded product to thermal degradation in the presence of nitrogen, quenching at 50 degrees C, soaking at low temperature in the presence of high pressure carbon dioxide, crystallizing, and foaming at high temperature. USE - Method of supercritical carbon dioxide foaming of polyester. ADVANTAGE - The method obtains nano-pore foaming polyester material.
