Silicone Self-Fusing Tape: High-Performance Industrial Sealing, Electrical Insulation for Railways & Beyond


When it comes to reliable insulation, sealing, and weatherproofing in high-demand environments, silicone self-fusing tape stands out as a trusted solution. Composed of advanced silicone, it immediately self-bonds when wrapped, providing a flawless, residue-free, air- and water-tight covering. Its adaptability lets it handle odd shapes, so it’s great for rapid leak repair and shielding against corrosion on various equipment.



Engineered for extreme temperature endurance, it works from -40°C to +250°C — ideal for engines, turbines, or other high-heat sites. The tape also offers high dielectric strength, often exceeding 20 kV/mm, making it perfect for electrical insulation, splicing, and cable bundling.

Within the railway sector, this tape finds use in traction motor cabling, pantographs, cable connections, and terminal kits. Moisture-proof, voltage-resistant, and vibration-absorbing, it is the solution for train electrics, signals, and outdoor rail gear. It protects systems from shorts, creepage, and electrical tracking in challenging climates.

Its durability against UV, ozone, chemicals, and weather makes it reliable for marine, solar, telecom, or HVAC needs, even when submerged.

Peroxide-curing processes result in higher mechanical strength and greater longevity for this tape. Outstanding elongation (over 300%) guarantees it wraps tightly and fuses well, even when pulled.

FR (Fire Retardant) grade silicone self-fusing tapes are available, making them well-suited for engineering or safety-critical use. Custom colour options are available, all meeting high standards for safe use. We manufacture silicone tapes in sizes from 25mm to 100mm wide and 0.5mm to 0.8mm thick.

The tape known as silicone self fusing tape, silicone Silicone Hose self adhesive tapes, silicone tapes etc are available for free trials on request.
