Abstract
For many applications with plastics the base systems are insufficient and use of reinforcing fillers is required. Glass and mica flakes are currently available for reinforcement. It has also been shown that properties of reinforced microcellular polyurethane are strongly affected by the void volume fraction. In this paper some experimental results on the applicability of far-infrared techniques to measure the state of dispersion and the concentration of mica and glass fillers in polyethylene and polyurethane are presented and discussed. It is shown that fillers can be analyzed with little perturbation from the presence of porosity, while the average orientation of the filler particles can be evaluated by varying the polarization or the angle of incidence of the far-infrared laser beam.
