Excellent chemical resistance, petrol resistance, oil resistance, temperature resistance, weathering resistance (UV / ozone resistant) & aging resistance (long-lived)
The Viton sponge rubber is made of hexafluoropropylene-vinylidene fluoride, is a copolymer and is a rubber compound for high-thermal and chemical-aggressive sealing applications. The sponge rubber is produced (extruded) in a special process (expansion) into a sponge rubber foam and has a predominantly open-cell structure with a closed outer skin. The rubber compound is characterized by excellent resistance to almost all media and a very high temperature resistance (up to + 250 ° C), as well as good mechanical properties, high tensile strength, high flame retardancy and low gas permeability. The resistance to oils, fats, gasoline, acids and alkalis is excellent.
The sponge rubber is a foam in the commercial hardness or density and adapts under light pressure immediately and very well to uneven surfaces. The good recovery behavior (i.e., the material returns to its original shape) allows for optimal sealing. A compression of the material from 30% to max. 50% before sealing is recommended, with a compression of more than 50% damaging the material structure and greatly reducing the recovery behavior.
