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


In industries where insulation, sealing, and weatherproofing are critical, silicone self-fusing tape proves its value time and again. Made from advanced silicone rubber, it bonds to itself instantly when stretched and wrapped, forming a seamless, air-tight and water-tight layer — without leaving any residue. Its adaptability lets it handle odd shapes, so it’s great for rapid leak repair and shielding against corrosion on various equipment.



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. High dielectric performance (20 kV/mm and up) ensures it can insulate, splice, or bundle cables safely.

In the railway industry, silicone self-fusing tape is extensively used in traction motor cables, pantograph lines, cable joints, and termination kits. Its ability to resist moisture ingress, high voltage, and mechanical vibrations makes it perfect for onboard electrical systems, signal boxes, and trackside installations. The tape safeguards against shorting, leakage, and tracking even during extreme weather.

Resistant to UV, ozone, oil, and solvents, it is built for lasting performance outdoors and underwater—ideal for marine gear, solar sites, telecom infrastructure, or HVAC.

On the technical side, peroxide curing gives the tape enhanced strength and a longer lifespan. With over 300% stretchability, it remains secure and tightly fused Silicone Hose in high-tension scenarios.

We have silicone self fusing tapes of FR(Fire retardant) grade which makes and keep it ideal in engineering applications. 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.
