AN INVESTIGATION OF MICROCELLULAR INJECTION MOULDING ON THE STRUCTURE-PROPERTY RELATIONSHIPS OF ENGINEERING THERMOPLASTICS USED IN EXTERIOR AUTOMOTIVE APPLICATIONS

摘要

The purpose of this study was to investigate the effect of MuCell processing on the structure-property relationships of critical engineering thermoplastics. Such techniques as differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), scanning electron microscopy (SEM) as well as a variety of standard testing equipment were used to show that through an effective design of experiment, the expected decrease in performance of key physical, mechanical and thermal properties can be minimised, and even improved in some cases.
