Abstract: |
The electrical conductive carbon blacklEPDM electromagnetic shielding composites which could be processed by extrusion were prepared using EPDM as matrix and conductive carbon black as conductive filler. The influence of type and addition level of carbon black and plasticizer on the properties of the obtained composites was investigated. It was found that the electrical conductivity of the composites was improved by using electrically conductive carbon black with higher structure and smaller particle size. As the addition level of conductive carbon black increased,the volume resistivity of the composites decreased. When the addition level of conductive carbon black was 18 phr,the volume resistivity of the composite was less than 10 Ω·cm. By adding 20 phr of paraffin oil,the Mooney viscosity of the composite could be reduced effectively |
