Specific direct current conductivity of insulation material at 0°C and 0 kV/mm electrical field strength. Often the symbol $\sigma$ is used.
The values were mainly taken from the book 'An Introduction to Materials Engineering and Science: For Chemical and Materials Engineers' chapter 8 by Brian S. Mitchell, Wiley Online Library, 2003 plus some papers.
