ELASTOSIL® R 402/65 OH

ELASTOSIL® R 402/65 OH is a high-consistency silicone rubber (HCR) that is optimized for extrusion. This transparent compound allows for high extrusion speeds and the production of high-quality tubes. The peroxide-cured vulcanizates made from this compound exhibit a unique combination of characteristics. It is noted for its good flexibility, high transparency, and mechanical properties. The compound can be easily pigmented with ELASTOSIL® Color Paste PT.

Application Details

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.

Processing

  • 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.
