✦ Synopsis

Styrene butadience rubber (SBR-1502) loaded with different concentrations of FEF carbon black was tested to find out the effect of pressure on its electrical properties during vulcanization.

Using the thermodynamically calculated values of the pressure coefficient (K), the thermoelastic coefficient (L = aT/aP) was also estimated and compared with that obtained by other workers. The thermoelastic coefficient was found to be strongly dependent on the carbon black concentration.
