KLINGER®top-graph 2000

Combines the advantages of fiber-reinforced gaskets and flexible graphite

KLINGER top-graph 2000 combines the advantages of fiber-reinforced gaskets with the key features of flexible graphite.

Basis

Graphite and synthetic fibers bonded with NBR.

Areas of application

Thanks to its high degree of inherent stability this material offers reliability in handling. Due to the high load bearing capacity and the low embrittlement, KLINGER top-graph 2000 is ideal for the use with steam and other demanding applications.

Key features

Utilization of graphite as filler
High Level of load bearing capacity

Benefits

Improved flexibility
Resists high surface pressure also at elevated temperatures
