Processing-Mechanical Property Relationship of Thin Microcellular PET Sheet Prepared by Compression Molding

摘要

This article presented processing-mechanical property relationship of thin microcellular poly(ethylene terephthlate)(PET)sheet prepared by compression molding.The results showed that the saturation time and the lower-plate temperature had more effects on the mechanical property.The upper-plate temperature and the PET thickness also had some effects on the mechanical property.The upper-plate temperature had more pronounced effect on the specific tensile strength than on any other mechanical parameters.Besides,there was little dependence of the mechanical property on the saturation pressure and the blowing agent content.
