| Abstract | ||||
| Reinforced Ethylene Propyline Diene Terpolymer, EPDM, and Nitrile Butadiene Rubber, NBR, were mixed with different concentrations of asodicarbonamide, ADC/K, as a foaming agent to obtain EPDM and NBR rubber foams. The investigated foams were subjected to electrical, A.C. and D.C, measurements. Electrical conduction mechanisms were studied. Poole- Frenkel and Schottky conduction mechanisms were detected. The dielectric permittivity and loss were found sensitive to oscillating field. It was found that the increase of foaming agent content affects markedly all the electrical parameters. | ||||
