RHEOLOGICAL AND MECHANICAL PROPERTIES OF POLYMER BLENDS, RADIOPAQUE FILLERS AND COUPLING AGENT

摘要

This work studied the effect of blending two different grades of thermoplastic polyurethanes with a constant percentage of radiopaque filler (bismuth subcarbonate) and varying percentages of filler. A titanate binding agent was added to the blend to investigate the impact of improved polymer/filler adhesion. The results showed that varying grades of thermoplastic polyurethane in conjunction with different filler loadings can modulate the physical properties of the compound.
