Does Garlock have dielectric breakdown values for gaskets?

Garlock has dielectric breakdown voltage test data available on our most popular gasketing styles.

Generally speaking, GYLON® styles and compressed sheet that does not use carbon or graphite fibers have high dielectric breakdown values. Under humid or wet conditions, Styles 3504 and 3565 are particularly resistant to dielectric breakdown.  We should mention that not all rubber materials are insulators.
