Safety Cables
- Application Details
- For flame resistant cable construction (safety cables). Cables containing ELASTOSIL® R 502/75 OH have successfully passed standards, like NFC 32070 CR1, BS 6387 CWZ, DIN 4102, part 12 (E30,-60,-90), UL 2196, EN 50200, IEC 60331-11, etc.
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.
