1. Flame-Retardant Products: This silicone is ideal for the production of flame-retardant components used in high-risk industries, ensuring safety and compliance with fire safety regulations.

2. Electrical Insulation: Suitable for manufacturing electrical insulators, wires, and connectors that require superior flame resistance and durability under extreme conditions.

3. Automotive Industry: Used for automotive parts that need to withstand heat and provide fire-resistant properties, such as seals and gaskets.

4. Consumer Electronics: Can be utilized in various electronic products requiring high resistance to heat, fire, and environmental stress.

5. Construction Materials: Ideal for sealing and insulating materials that need to meet strict fire safety standards.

To process High Strength Flame-Retardant HCR Silicone, mix the rubber with the appropriate curing agents. Vulcanize the material at 175°C for 5 minutes under 15 MPa pressure. After vulcanization, ensure proper cooling to maintain the material's flame resistance, flexibility, and mechanical properties. This ensures the silicone rubber retains its high strength and resilience, especially for fire-sensitive applications.
