Thermoseal Klingersil C-7400 satisfies both sealing and electrical requirements. C-7400 is resistant to moderate caustics and acids which makes it suitable for paper mills. It can also act as an insulator or barrier to the flow of electrons from one flange to another due to its high dielectric strength.

This material is manufactured with synthetic fiber reinforced with an EPDM binder.
