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

For dependable insulation, sealing, and protection in demanding settings, silicone self-fusing tape is the preferred choice. 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. Its impressive dielectric strength, typically above 20 kV/mm, makes it the go-to for electrical insulation, cable splicing, or wire 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.

Silicone self fusing tape resists UV radiation, ozone, oil, solvents, and harsh weather making it a long-term solution for outdoor and submerged applications, including marine equipment, solar power installations, telecom towers and HVAC systems.

Peroxide-curing processes result in higher mechanical strength and greater longevity for this tape. Outstanding elongation (over 300%) Silicone Insulation Sleeve 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. The same can be provided in all custom colours without compromising the quality and is more safe to use. Tape sizes can be customised from 25mm to 100mm width and 0.5mm to 0.8mm thickness.

Samples of our silicone self-fusing tape (also called silicone self-adhesive or silicone tapes) are available on request.
