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. Crafted from high-grade silicone rubber, this tape fuses to itself the moment it's stretched and applied, creating a continuous, air- and water-tight seal with zero adhesive residue. The tape’s flexibility allows it to wrap neatly around complex forms, making it perfect for quick leak fixes and safeguarding hoses, pipes, or ducts from corrosion.
With remarkable heat resistance, it performs flawlessly from -40°C up to +250°C, making it suitable for engine bays, turbines, or hot zones like heating elements. The tape also offers high dielectric strength, often exceeding 20 kV/mm, making it perfect for electrical insulation, splicing, and cable bundling.
In the railway industry, silicone self-fusing tape is extensively used in traction motor cables, pantograph lines, cable joints, and termination kits. Because it blocks moisture, stands up to high voltage, and absorbs vibration, it’s ideal for onboard wiring, signal systems, or installations along the tracks. The tape safeguards against shorting, leakage, and tracking even during extreme weather.
Its durability against UV, ozone, chemicals, and weather makes it reliable for marine, solar, telecom, or HVAC needs, even when submerged.
On the technical side, peroxide curing gives the tape enhanced strength and a longer lifespan. 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. The same can be provided in all custom colours without compromising the quality and is more safe to use. Tape sizes can be Silicone Insulation Sleeve 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.
