General Properties and Applications

A high-performance sealing sheet containing a specially selected combination of aramid fibers and graphite. It is highly flexible, allowing it to conform effectively to the surfaces being sealed.

It is particularly recommended for use in steam systems. It is resistant to, among other things, water, fuels, and oils.

Material

The GAMBIT AF-200 G gasket sheet is made from:

• KEVLAR® aramid fibers
• graphite
• mineral fibers
• fillers

These components are bound together with an NBR rubber-based binder.
