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. 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. It conforms easily around irregular shapes and is ideal for emergency leak repairs & corrosion protection on hoses, pipes, and ducts.



It has exceptional thermal stability, operates effectively in temperatures ranging from -40°C to +250°C, making it ideal for high-heat environments such as engine compartments, turbines, or 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. 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.

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.

We have silicone self fusing tapes of FR(Fire retardant) grade Silicone Insulation Sleeve 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. 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 self adhesive tapes, silicone tapes etc are available for free trials on request.
