Our Silicone Self-Fusing Tape, also known as self-amalgamating silicone tape or silicone rescue tape, is a high-performance insulating and sealing tape designed for electrical, industrial, marine, and repair applications.
Unlike conventional adhesive tapes, this linerless silicone tape contains no adhesive. When stretched and wrapped, it chemically bonds to itself, forming a seamless, waterproof, and flexible insulation layer.
Made from high-quality silicone rubber, it offers excellent electrical insulation, weather resistance, and flexibility under extreme conditions. It is widely used for cable repair, wire protection, emergency sealing, and industrial maintenance.
Available Colors: Black, Blue, Clear, Green, Gray, Red, White, and Yellow. Custom colors are available upon request.

Key Features
- Adhesive-Free Self-Fusing: Bonds to itself without any sticky residue, ensuring clean and reliable insulation.
- Extreme Temperature Resistance: Withstands continuous service from -50°C to +260°C, ideal for high-heat environments.
- Superior Waterproofing: Provides a moisture-tight seal; passes 720 hours of water immersion without loosening or water ingress.
- Excellent Electrical Insulation: High dielectric strength of ≥30 kV/mm, suitable for high-voltage cable repair.
- Corrosion & Shock Absorption: Protects metal surfaces from corrosion and dampens vibration in marine and automotive applications.
Applications
Electrical Cable Insulation
Suitable for high-voltage cable splicing (up to 69kV), motor leads, busbars, and electrical connections in power distribution systems, requiring reliable insulation and moisture protection.
Marine & Automotive Wiring
Provides waterproof and corrosion-resistant protection for marine engines, automotive wire harnesses, and electrical connections exposed to moisture, vibration, and harsh environments.
Industrial Maintenance & Equipment Repair
Designed for on-site repairs in industrial environments, providing waterproof sealing and insulation for cables, hoses, machinery components, and electrical connections.
Waterproof Sealing & Emergency Repair
Suitable for temporary sealing of hoses, pipes, and industrial equipment exposed to moisture or leakage.
High-Temperature Equipment Wrapping
Protects heating elements, boiler pipes, furnace components, and other high-temperature equipment (up to +260°C) where heat resistance and electrical insulation are required.
Sports & Tool Grips
Ideal for anti-slip wrapping on sports equipment (such as tennis rackets, hockey sticks, and bicycle handlebars) and tool handles. The self-fusing silicone tape provides a comfortable, non-slip grip without leaving sticky residue on hands or equipment.
