Datenblätter
ELASTOSIL® R 420 /50 S is a general purpose grade that may be used for producing molded, extruded or calendered articles like seals, gaskets, sheets, tubings and profiles.
Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances.
The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous incorporation is a must, but please avoid temperatures >30°C along the incorporation process in order to maintain best processing behavior. Pot life is depending on the used peroxide and storage condition.
