- Application Details
- Cable insulations for household, automotive, railway, marine and aerospace applications where high flame retardancy is required.
- 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.

- Cured Properties
- Properties
- The color of the rubber base is white. Colors will not match the RAL color codes of the masterbatches used in paste or pellet form in the compound (pastel colors).
- This product can be used within a temperature range of - 55 °C to + 210 °C. The addition of heat stabilizers at service temperatures of more than 180 °C is recommended.
- Note
Cure conditions (post-cured 4 h / 200 °C): 1.8 % ELASTOSIL® AUX Crosslinker E (50% paste of bis-(2,4-dichlorobenzoyl)-peroxide in silicone fluid); 10 min / 135°C in press
