Low-density polyethylene/ ethylene-propylene-diene terpolymer ( LDPE/EPDM) blends and LDPE/ethylene-ethyl acrylate (EEA) blends were chosen as objects of study. Their positive temperature coefficient ( PTC ) phenomena and their distinctive aspects were described. The explanations were given from the
The dependence of electrical resistivities on the temperature of different polymer systems (including rubbers and plastic/rubber blends) loaded with carbon blacks (including oxidized and normal carbon blacks) were studied. We found that polymer-carbon black interactions could greatly influence the e
Low-density polyethylene/ethylene-propylene-diene terpolymer/carbon black blends were irradiated in air with a 6oCo y ray or an electron beam accelerator. The absorbed dose ranged from 1-400 Mrad. The influences of irradiation on positive temperature coefficient behavior of the blends were analyzed.
## Abstract Several carbon black (CB)βfilled binary polymer blends were prepared in Haake rheometer. Distribution states of CB and effect of morphology on the electric conductivity of different ternary composites were investigated. Under our experimental condition CB particles located preferentiall
