Cardboard Hydraulic Klingersil TOP-GRAPH 2000
Manufactured using a revolutionary process that gives hydraulic cardboard with graphite fibers unprecedented properties.. Thanks to high surface compressive strength and low brittleness, this material is suitable for steam usage and other special applications.
Composition
Sealing material composed of graphite and synthetic fibers, bonded with NBR.
Areas of application
The material impresses with its ease of handling., high surface compressive strength and low brittleness at temperatures up to 300°C. These properties provide Top-Graph 2000 great resistance to damage during assembly and operation, prevents pressure drop of screws and formation of cracks at high temperature. The material is suitable for use in steam up to 300°C and, depending on application area, temperatures up to 500°C are possible.
O KLINGERSIL® Top-Graph 2000 2000 combines the characteristics of reinforced gaskets with synthetic fibers (preferred by specialists) with the graphite fiber.
