Abstract
A new method to determine the dry rubber content (DRC) of natural rubber latex using a capacitive transducer is presented. The capacitance of a capacitor is directly proportional to the area of the plates permittivity of the medium and inversely proportional to the separation between the plates. If the area of the plates and the separation between them are kept constant the capacitance is directly proportional to the permittivity of the medium. Based on this physical principle a capacitive transducer was specially designed and fabricated. The capacitance of the capacitor with latex samples as the dielectric was measured with a high impedance LCR meter. Simultaneously the DRC of the same latex samples was determined following standard laboratory procedures. Statistical analysis of the results showed that there was a good correlation between the capacitance with Hevea latex as the dielectric and the corresponding DRC values. Related parameters such as dissipation factor electrical resistivity impedance and susceptibility were found to be proportional to the DRC values of latex.
