General properties and applications

A high-performance sealing sheet containing a specially selected combination of aramid fibres and graphite. It is characterised by high flexibility, which enables it to conform effectively to the surfaces being sealed.

Particularly recommended for use in steam systems. Resistant to, amongst other things, water, fuels and oils.

Material

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

• KEVLAR® aramid fibres
• graphite
• mineral fibres
• fillers

The components are bound together by an NBR rubber-based binder.
