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. 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.

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. It maintains excellent elongation (over 300%), ensuring secure wrapping and tight fusion even under tension.

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