Material
The GF gasket is a high temperature, asbestos-free vitreous/glass fiber gasket, with a self-adhesive side. Because of its excellent biological solubility is it classified as not carcinogenic. For this reason, a hazardous substance classification is unnecessary. In view of its temperature resistance and low thermal conductivity, this material is particularly well suited for insulation purposes. Self-adhesive, asbestos-free, high temperature glass fiber gasket. Fiber diameters 3,2 µm. Color: white. The product is halogen-free.  Adhesive: acryl dispersion. Protective foil: siliconized film (*), white.

(*) All self-adhesive products are usually fitted with a siliconized protective foil applied over the bounding surface. To install the product this foil must be removed: it is therefore not part of the product. The gasket material itself is silicon-free. It is possible however, that silicon traces are detected, as they can be transmitted to other parts during handling. An absolute silicon-free guarantee can, for that reason, not be given.

Operating Temperatures    
≈ + 1.100 °C: Fibers temperature resistance.
≈ + 250 °C: Temperature at which the bonding agent holding the fibers together loses its adhesive properties.
≈ + 200 °C: Temperature at which the self-adhesive side of the gasket loses its adhesive properties.

In view of the above it is recommended to replace the GF gaskets on all METU-SYSTEM products having been subjected to temperatures above 200°C, as the gasket might have lost its mechanical properties and crumble.

Caution
Fibers can be soaked with liquids. The resistances are valid for the fibers only, and not for the adhesives or other components. The adhesives have only a limited resistance against chemicals. 

Oil Resistance
The fibers themselves are oil-resistant. The gasket will however absorb oil, negatively influencing the adhesive properties of the bonding agent. Under such circumstances, the temperature resistances can also be affected.

Chemicals are available in very different qualities. Their properties vary depending on their concentration, operating temperatures, possible mix with other chemicals and the eventual presence of impurities. This is why gasket manufacturers only provide general information about the resistance of their products to various chemicals. In view of the above it is advisable that the client runs some tests in order to assess if the gaskets are suitable for the intended application. We regret not being able to provide more precise information.
