VR 100
Material
VR 100 is an asbestos-free gasket material. It consists of carbon fibers and other asbestos substitutes that are resistant to high temperatures and are processed with high-grade elastomers under elevated pressure and temperatures.
Properties
VR 100 exhibits very good temperature resistance together with high mechanical strength, as shown by its high values for residual stress and tensile strength. It is ideally suited for sealing gases and liquids, and also features high chemical resistance, e.g. with lyes.
Application
- in the petroleum and chemical processing industries
- for pipe flanges to DIN and ANSI, apparatus, pumps, heat exchangers,
and fittings in industrial applications - for sealing engine, transmission, hydraulic, and refrigerating oils
- for sealing fuels, mixtures of water, antifreeze & corrosion inhibitors
- for sealing leaches, lyes, and solvents
Surfaces
As standard, both sides of VR 100 are coated with a non-stick layer that greatly facilitates disassembly. In most cases, additional surface treatment is unnecessary.

The data quoted above are valid for the material “as delivered” without any additional treatment. In view of the countless possible installation and operating conditions, definitive conclusions cannot be drawn for all applications regarding the behavior in a sealed joint.
Therefore, we do not give any warranty for technical data, as they do not represent assured characteristics. If you have any doubt, please contact us and specify the exact operating conditions.
