Effects of contaminations in rubber latex on relative permittivity at 0.5–2.0 GHz

This paper proposes an analysis on the effects of contaminants and studies the contamination detection in rubber latex with relative permittivity at 0.5-2.0 GHz. In order to develop a mathematical model for detecting contaminants in rubber latex, it can apply to the DRC measurement system which has been created earlier. The DRC measurement system is designed to be the mostly operate at 1.0 GHz. From this experiment, the percentage of dry rubber content (DRC) is increasing with the amount of contaminants. Thus, the contaminated latex is not detected by the Total Solid Content method (TSC). The contaminated latex can be detected by the relative permittivity. In this result, the dielectric loss factor can distinguish of contaminated latex better than dielectric constant. Finally, the DRC measurement systems can be measured DRC and detected contamination in rubber latex on a single device in the future.
