Saint-Gobain DYNAFOAM (member of the Norseal product range) is a mono-component foam in place gasketing and cushioning material. It is foamed by mixing with Nitrogen (less than 5ppm humidity) and cures by reacting with moisture, creating low density thermoset, elastomeric, foamed gaskets.
This product range has been developed to seal out water, air or dust as well as decouple the noise vibrations. Thanks to its semi-closed cell structure, DYNAFOAM creates efficient water seal with only 30% compression. This cell structure generates soft and conformable gaskets avoiding thin walled plastic parts to distort when compressing the gasket. It shows a low water absorption and extremely tough skin, which prevent the gasket from being torn under rough assembly conditions.
Thanks to its engineered viscosity and its mechanical foaming, DYNAFOAM exhibits excellent thixotropic behavior allowing 3-dimensional and upside-down applications. The desired gasket height can be achieved with or without a groove, allowing the maximum design flexibility for engineers.
DYNAFOAM products are packed in a multilayer aluminum bag to prevent any leakage during transport and manipulation, as well as protecting the material from the humidity:
