Flame-Retardant Self-Fusing Silicone Electrical Tape
A high-performance flame-retardant insulation material manufactured from silicone raw rubber blended with silicon nitride carbon powder. Produced through advanced mixing, extrusion, and vulcanization processes, this tape offers exceptional self-adhesive properties, superior sealing performance, and reliable electrical insulation.
Primary Applications
Electrical Systems Protection
- Substations and power plants: Insulation for exposed copper parts, electrical connectors, cable joints, and switchgear busbars
- Transformers, motor lead wires, and insulation sealing for rubber/plastic cable terminals
Engineering Sealing & Waterproofing
- Construction: Sealing structural joints, underground projects, and overlaps of polymer waterproof membranes
- Municipal engineering: Tunnel joint sealing, seawater treatment equipment protection
- Panel systems: Airtight waterproofing and shock absorption for color profiled/sunlight panel joints
Operating Environment
- Temperature Range: -60°C to +180°C (stable performance in extreme conditions)
- Weather Resistance: UV-resistant, ozone-resistant, and aging-resistant for long-term outdoor exposure
- Chemical Resistance: Anti-corrosion, pollution-resistant, and solvent-compatible for industrial environments
Key Advantages
- Self-Adhesive Properties: Non-tacky surface; fuses into seamless layer after wrapping (waterproof/dustproof); residue-free removal
- Physical Flexibility: High elasticity; conforms to irregular shapes and contours
- Long-Term Protection: Flame retardancy rated 94V0 (GB/T 10707-2008 compliant)
- Environmental Adaptability: Suitable for high-humidity, saline, and wide-temperature-difference environments
