VR 60 |
|
| Material |
VR 60 is an asbestos-free gasket material. It is composed of aramide fibres and other asbestos substitutes which are resistant to high temperatures. These substitutes are processed with high-grade elastomers under elevated pressure and temperature. |
| Properties |
The gasket material is physiologically safe and does not contain any color pigments.
On the one hand, this economical gasket material is conformable and flexible, which ensures adequate sealing even with low surface pressure. On the other hand, it provides adequately high stress resistance coupled with good gas sealability.
In addition, VR 60 is resistant to solvents, oils, fuels, water and many other media. |
| Application |
For sealing joints which are subject to moderate thermal and mechanical stress: for fittings in HVAC installations, gas units and heaters; for lightweight components and flanges; for apparatus, transmissions, pumps; for sealing lightweight components with comparatively low surface pressure, e.g. transmissions, valve covers, oil pans and covers in internal combustion engines.
As VR 60 is physiologically safe, it may be used particularly in contact with drinking water and food. |
| Surfaces |
The standard version of VR 60 has a non-stick top and bottom layer with a high coefficient of friction. This facilitates dismantling. Additional surface treatment is unnecessary in most cases. |

The data quoted above are valid for the material "as delivered" without any additional treatment. In view of the multiplicity of possible installation and operating conditions, definitive conclusions cannot be drawn for all applications regarding the behavior in a sealing joint. For this reason, we do not give any warranty for technical data. They do not represent warranted properties. If you have any doubt, please contact us and specify exact operating conditions. |
