Application:

Flexible Graphite is unaffected by heat over a wide range of temperatures. It exhibits low electrical resistivity and high thermal conductivity and is suitable for cryogenic temperatures and is available in several styles. These include homogeneous sheet and laminated styles with various types of core materials. Durlon® Flexible Graphite can also be special ordered with various inhibitors, grades of graphite and core materials to suit specific critical applications.

Types:

FGS95: Standard industrial grade sheet containing no binders or resins. This product is used in industrial applications such as oil refineries, power plants and chemical process plants.

FGL316: Standard industrial grade sheet laminated with an adhesive bond on both sides of a 0.002” thick 316 stainless steel foil core. This product is used where high performance and handling are important.

FGT316: Standard industrial grade sheet mechanically bonded on both sides of a 0.004” thick 316 stainless steel tang core. This product is used where stresses and pressures are high and improved handling is important.

FGM316: Inhibited grade sheet laminated with multiple layers of 0.004” thick 316 stainless steel foil core. This product is used in applications with high mechanical stress or pressure, above average burst resistance, exceptional rigidity, fire safe and suitable to cut gaskets with narrow strips.
